Complete answer:
The meaning of attrition is ‘gradually making something weaker and destroying it, especially the strength or confidence of an enemy by repeatedly attacking it’. And we must find the correct answer from the options given whose meaning is the same as that of attrition.
Option A) Attraction - is an incorrect answer because the meaning of attraction is ‘the action or power of evoking interest in or liking for someone or something or appeal or interest or feature’ and this is not the synonym of the word attrition because their meanings are not same. Thus, this is an incorrect answer.
Option B) Suffering - is an incorrect answer because the meaning of suffering is ‘the state of undergoing pain, distress, or hardship’ and this is not the synonym of the word attrition because their meanings are not the same. Thus, this is an incorrect answer.
Option C) Decline - is the correct answer because the meaning of decline is ‘decrease or reduce or refuse or fewer’ and this is the synonym of the word attrition and they can be used in place of each other because they have similar meaning. Thus, this is the correct answer.
Option D) Friction - is an incorrect answer because the meaning of friction is ‘the resistance that one surface or object encounters when moving over another or rubbing or chafing’ and this is not the synonym of the word attrition because their meanings are not same. Thus, this is an incorrect answer.

Hence, the correct answer is Option ‘ C’.
