Right answer is (b) path from root to the leat yields the string
 
Easiest explanation – A trie is an ordered tree where (i) the root represents an empty string(“”) (ii) each node other than root is labeled with a character (iii) the children of a nodes are lexicographically ordered (iv) the paths from the leaves to the root yields the strings.
