Question

Fill in the blank with a suitable conjunction:
I'd feel very angry _________ somebody broke into my house.

• A. if
  
• B. whether
• C. otherwise
• D. after

Answer 1

The correct option is A if

Option A: The given sentence is a type 2 conditional.

It states a hypothetical condition 'somebody broke into my house' and its probable result 'I would feel very angry'. In this type, the hypothetical clause is an if-clause. 'If' refers to a condition.

Hence option A is correct.

('I'd' is a contraction of 'I would'.)

Options B, C and D: 'Whether' refers to alternatives, 'otherwise' refers to 'other circumstances' and 'after' refers to time.

These words do not indicate condition. The meaning is necessary as the result is also hypothetical 'would'. Hence these options are incorrect.
