1."will be able to"(d)

Use 'will be able to' for future ability. 'Can' and 'could' cannot be used with 'will'.

2."was able to"(b)

For a specific past achievement (one successful action), use 'was/were able to', not 'could'. He succeeded on that particular occasion.

3."won't be able to"(c)

Use 'won't be able to' for future inability. 'Can't able to' and 'don't able to' are not grammatically correct.

4."haven't been able to"(a)

Use 'haven't been able to' with the present perfect. 'Since they started' requires present perfect tense.

5."has been able to"(d)

'Since the surgery' requires present perfect. Use 'has been able to' to show ability from a past point until now.
