The correct options for the dialogue would be:
A: Hi, Terry. Have you got any plans for the weekend?
B: Yes. I'm watching the football.
A: See the Champions League match?
B: Yes. Do you want to come?
A: I'd love to. I'll ask my mum if it's OK.
B: Great. We'll buy the tickets tomorrow morning. I can get you one if you like.
A: OK. I'll call you this afternoon.
Here are the corrections made:
- "I watch" to "I'm watching" (to indicate a future plan).
- "see the Champions League match?" (no correction needed; it's fine as is).
- "I'll ask" instead of "I ask" (future intention).
- "We'll buy" instead of "we buy" (future intention).
- "I can get you one" instead of "I c get you one" (correcting the typo and making it a full sentence).
- "I’ll call" instead of "I call" (future intention).
