Correct Answer :- c
Explanation : The worm can be considered resembling a helical gear with a high helix angle. For extremely high helix angles, there is one continuous tooth or thread. For slightly smaller angles, there can be two, three or even more threads.
The worm wheel is similar in appearance to a spur gear the worm gear is in the form of a screw generally with a flank angle of 20°.
Self-locking means it is not possible to drive the worm using the worm wheel, and this feature is used in such things as reversing prevention systems.

Explanation:
High Spiral Angle:
- The worm in a worm and worm wheel drive typically has a high spiral angle, which allows for smooth and efficient power transmission.
Used for Very High Speed Reduction:
- This type of drive is commonly used for very high speed reduction applications, where the worm wheel is driven by the worm to achieve the desired output speed.
Worm Wheel as the Driver:
- In a worm and worm wheel drive, the worm wheel is the driver component that transfers power from the worm to the driven mechanism.
Therefore, the correct options are 1, 2, and 4, as the worm has a high spiral angle, the worm wheel also has a high spiral angle, and the worm wheel is the driver in this type of drive system.
