Here are the best options for each fill-in-the-blank question based on context:

1) We need to talk more about **C. where to go** for the summer vacation before July.
- This makes sense as discussing a vacation usually involves deciding on a destination.

2) There’s little **B. coverage** of foreign news in today’s paper.
- "Coverage" fits best in this context as it refers to the extent to which news is reported in the media.

3) That pipe **A. has been leaking** for ages - we must get it mended.
- "Has been leaking" indicates a continuous action that started in the past and is still relevant now.

So the answers are:
1) C
2) B
3) A
