1.You’ll have the opportunity to ask/ for asking/of asking any questions at the end.
2.At least give her the opportunity to explain/for explaining/of explaining what happened.
3.I’d like to take this opportunity to thank/for thanking/of thanking my colleagues for their support.
You will choose (a), (b) or ©?
a.to-inf (to ask, to explain, to thank)
b.for +ing (for asking, for explaining, for thanking)
c.of + ing (of asking, of explaining, of thanking)
Is there a case that you choose both (a and b, b and c, a and c)(that means both are correct and have the same meaning) or all (a, b, c)(that means all are correct and have the same meaning)?
Is there a rule? (when using “to”, when using “for”, when using “of”?)
