Question

Complete the given sentence using an appropriate conjunction:

________ you bought some new clothes, you'd look much nicer.

• A. When
  
• B. While
• C. If
• D. Whether

Answer 1

The correct option is C If

Option C:

The given sentence is a type 2 conditional.

It states a hypothetical condition 'you bought some nice clothes' and its probable result 'you'd look much nicer'. In this type, the hypothetical clause is an if-clause. 'If' refers to a condition.

Hence option C is correct.

Options A, B and D: 'When' refers to time, 'while' refers to 'the time when a simultaneous action takes place' and 'whether' refers to alternatives.

These words do not indicate condition. The meaning is necessary as the result is also hypothetical 'would' ('you'd' is a contraction of 'you would'). Hence these options are incorrect.
