Agree to/on a suitable date

Hi teachers,

These questions appeared in an exam paper.
Choose the correct options.
Let’s try to agree … a suitable date. (on,to,at,of) on or to but I am not sure which option is the best?

A: Little money is better than no money.
B: A little money is better than no money.
C: The little money is better than no money.
I think B is correct.

“on”. You could also omit the preposition altogether.

Yes, B.

I should mention that “agree to a date” is also possible, but it suggests that one person proposes a date for the other to agree to or not, and does not fit the cooperative feel of “let’s try”.

For example: “I can’t get him to agree to a date”.

Thank you very much, Dozy
