Answer:
D). 'On the contrary'
Explanation:
As per the question, option D displays the phrase i.e. 'on the contrary' from the given passage that indicates an opposing or contrary thought as this phrase signals the beginning of the ideas in the passage that would contradict the previous ideas presented. <u>This phrase introduces the alternative idea that challenges the prior idea which states that 'every act of kindness is in fact purely selfish' by offering the contradictory claim that 'selfishly motivated giving has done a lot of good in the world'.</u> Thus, the phrase 'on the contrary' signifies contrast and hence, <u>option D</u> is the correct answer.
1) The wrong sentence is D. In that case you don't need the possessive pronoum YOUR because what you need is a personal pronoun. YOU'RE is the correct form. However, as it is a question, the most suitable position for the pronoun is after the verb to be.
2) The incorrect sentence is C. In that case you need the pronoun THERE because the verb comes before its subject.
3) The incorrect sentence is D. In that sentence a personal pronoun +verb to be is needed. As it is talking about the weather the correct way is IT'S. The possessive adjective or possessive pronoun (its) is not correct for that context.
4) The wrong pronoun is in sentence B. When the sentence starts with the preposition TO you need the pronoun WHOM. The preposition can also be at the end of the sentence.
