Four pairs of words are given here out of which the words in three pairs bear a certain common relationship. Choose the pair in which the words are differently related.

Wine : Grapes Paper : Pulp Shoes : Leather Wheat : Crop

Wheat : Crop

The former item is made from the latter one i.e. wine is made from grapes, paper is made from pulp, shoes is made from leather. But, wheat is not made from crop. Thus, option 4 stands to be correct.
