Correct option is A
Given:
Relationship: MAN : CROWD — a crowd is a collection of many men (many individuals of that kind).
Logic:
Analogy of part-to-collection (singular → group of the same kind). So we look for the word that denotes a group/collection of trees.
Solution:
A forest is a collection of many trees. The other options (fruit, branch, root) are parts or products of a tree, not a group of trees.
Correct Answer: (a) FOREST
