Question

1. I said to her, "Are you fond of swimming?"

2. He asked her if she was fond of swimming.

3. He asked her if she 'is' fond of swimming.
-------------------------------
#1 can be changed into #2. What about #3? If we use 'is,' is it incorrect?

Answer 1

Both 2 and 3 are correct, but with slightly different meanings.

2 seems to be asking about how she felt in the past (which may or may not apply to the present).

3 is asking how she feels about swimming now -- at this time in her life.
