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?
a. (nothing)
b. do
c. do so
d. do it
e. do that
f. play
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?
