SOLUTION

There are some verbs which cannot be written in continuous form or they are rarely used in this form. These are called non-continuous verbs. 

Some of these verbs are:

Abstract verbs:  Be, want, cost, need, care, contain, owe, exist etc.

Possession verbs: Own, belong, possess etc.

Emotion Verbs: Like, love, hate, dislike, fear, envy etc.;

Example: She needs help. Not She is needing help.

He loves to read. Not He is loving to read.

Therefore, the verb form “wanting” is incorrect in the sentence and must be replaced by “wanted”. Option C is incorrect as the sentence is of past tense.
