Hint: Synonym is a word that means the same as the given word. The given word is ‘urge’, which means wish, need, or longing. One must look for words synonymous to the given word, for the correct answer.

Complete step-by-step answer:

The given word ‘urge’ means yearning or compulsion. Option a “impulse” means instinct or want, which is close in meaning to the given word, but not exactly the same, hence option ‘a’ is an incorrect option. Option b, “courage” means bravery or valor, which is irrelevant to the given word and has no relation to the context, hence is an incorrect option. Option c, ‘desire’ means need or longing, which is synonymous with the given word. Hence, option c is the correct answer. Option d, ‘ability’ means capacity, potential, or faculty, which is irrelevant to the given word and has meaning in the given context, hence is incorrect as well. Option c is the correct choice.

Note: Here, one must know the meanings of the words given in the options as well as the question. Options ‘a’ and ‘c’ might be confusing choices, one must be careful while choosing the correct answer.
