Answer:
A couple produces (d) purely rotational motion.
Explanation:
A couple mainly comprises of two parallel forces which are both equal and opposite. There is no line of action and hence it produces only rotational motion.
The resultant force generated from a couple is always zero. However, the resultant is not zero as it is a moment.
