A: Did you play tennis last weekend?
B: No, I wasn't feeling so well, so I decided not to _____.
What CAN'T you say in the blank?
c. do so
d. do it
e. do that
g. play tennis
h. play tennis last weekend
Why do I ask this question? Because I know that you can end the sentence with "to" as in (a). And I also know that you can add "do so/it/that" after "to". And I also know that you can repeat the verb phrase with or without "last weekend".
But I can't find a rule that you can omit the object and just use "play" as in (f), although somehow (f) does sound fine to my ears.
When can we end the sentence with a lexical verb (e.g., play) and omit its object (e.g., tennis)?
Could someone find me some authoritative source on this particular point?
