Assertion is true as smooth muscles are non-striated, and are fusiform (elongated and spindle-shaped, pointed or tapered at ends and broad in the middle). Smooth muscles have a centrally located single oval nucleus. Reason is true as smooth muscles are involuntary in their activity, i.e. their functioning cannot be directly controlled. Assertion and Reason are true, but Reason is not the correct explanation for assertion.

And Reason are correct and Reason is the correct explanation of the Assertion.
b)If both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
c)If Assertion is correct but Reason is incorrect.
d)If both Assertion and Reason are incorrect.

The correct answer is a) If both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

Explanation: Smooth muscle fibers are indeed unstriated, fusiform (spindle-shaped), and uninucleate. They do not have the striations seen in skeletal muscle fibers. They are also involuntary in function, meaning they are not under conscious control. The reason for this is that smooth muscles are controlled by the autonomic nervous system and hormones, rather than being controlled by conscious effort. Therefore, Reason correctly explains why smooth muscle fibers are involuntary in function.
