Rangeomorphs had no mouths, guts, arms, legs or reproductive organs, but an ancient "network" of strings may have helped them dominate the ocean floor anyway. In a study published in the journal Current Biology, researchers looked at hundreds of rangeomorphs — bizarre, fern-like animals that lived in large colonies on the bottom of the ocean from about 571 million to 541 million years ago — fossilized along the coast of Newfoundland, Canada. To the team's surprise, many of the fossil specimens appeared to be connected to each other by long, string-like filaments never seen among animals this old. Individual filaments spanned anywhere from a few inches to 13 feet (4 meters) in length and connected rangeomorphs from seven different species, forming what lead study author Alexander Liu called a primitive ‘social network’ of deep-sea dwellers.Scientists think the creatures dug into the mud on the ocean floor, passively sucking nutrients out of the water using symmetrical, leaf-like branches. Their methods worked well, apparently, as rangeomorph colonies dominated huge plots of the seafloor for 30 million years. Different species ranged from less than 1 inch (0.02 m) to 6.5 feet (2 m) in length, and some may have physically changed shape to better capitalize on the nutrients available around them. You could reasonably call rangeomorphs the ‘mighty morphin flower rangers’ of the Ediacaran and annoy only a few scientists in the process.Because rangeomorphs never really moved around, the fossil record includes entire colonies of the creatures preserved as they actually lived. When Liu and his colleagues found fossilized filaments connecting rangeomorphs at 38 different dig sites, it became clear that this sinewy ‘network’ played an important role in connecting individual colony members.That role, however, remains a mystery. The filaments may have helped stabilize colony members against strong currents, the authors hypothesized, making each colony into a sort of living picket fence. Perhaps the filaments were used to transfer nutrients from animal to animal, sort of how trees connected at the roots can share resources today. Or perhaps the links were a tool for clonal reproduction, a type of asexual reproduction where the parent organism creates multiple identical clones of itself. This would have allowed rangeomorphs to spread across large sections of the seafloor very rapidly.
Q. How the network of Rangeomorphs played an important role in connecting individual colony members?
  • a)
    As they sucked the nutrients out of the water using symmetrical, leaf-like branches
  • b)
    As they dominated the ocean floor using their might
  • c)
    As the old filaments framed by them made them able to connect at 38 different dig sites
  • d)
    As they colonized the maximum area of the ocean floor
Correct answer is option 'C'. Can you explain this answer?

Directions: Kindly read the passage carefully and answer the question...
As the old filaments framed by them made them able to connect at 38 different dig sites
As it is clearly expressed in the third paragraph that the scientist Liu and his colleagues had found filaments that were made by the rangemorphs in order to connect with each other at 38 different places. Option A and option B are correct statements but irrelevant to the question asked. Option D is completely absurd.
Hence C is the correct answer.
