The correct option is D with, in
'With' means 'in relation to a person'. It agrees with the first sentence, it is in relation with a person 'you'.
'About' means 'on the subject of, concerning'.
But, this word does not form a complete thought.
Hence OPTION A is incorrect.
'Along' means 'moving in a direction'.
This meaning isn't relevant to the first sentence. Hence OPTION B is incorrect.
'In' indicates a condition or aspect based on which a judgement is made, it refers to the noun 'opinion' here (opinion is a view or judgement).
Since 'with' and 'in' both agree to the sentences, OPTION C is correct.
OPTION D: 'In' does not refer to the noun in the first sentence 'you'.
'Within' means 'inside something' or 'in the limits of'. Both these meanings do not apply to the second sentence.
Hence option D is incorrect.
