He had never shown an urge to fly.
(Replace the underlined word with a synonym)
While Hariya is affectionately brought up from its injury days, it also seems a bit odd that it does not have the urge to fly. Naturally, a bird shows a desperation to fly away after several days of being held up, which isn’t shown here.
Thus the word urge, literally and logically, as given In the passage would mean the word ‘desire’, as mentioned in Option C, and can be replaced by the same. Urge and desire depict something that needs to be done with passion and in Hariya’s case, the same is flying.
The other options ‘impulse’ would mean intuition, while ‘courage’ and ‘ability’ would mean the qualities of someone rather than being a verb to act.
