Answer : 1. "(1)"
Explanation :
Answer: A) (1) Explanation: The error lies in part (1). As the phrase 'as much as' needs to be replaced with 'much as I'. This is because we use 'as much as' for comparing two qualities or things. But here in the given sentence a contrast is given in the latter part of the sentence. So we need a conjunction like 'even though' 'although' etc... 'Much as I' also serves the same purpose.
