Number of ACT scores you wish to report??

I took the ACT three times(April, October, and December).
Since my December test result came out in January 1, I have already sent my April and October test results to all colleges I’m applying.
However, all my highest scores turn out to be the scores in December.
Therefore, the scores indicated on the common app are all December scores.
Should I say 1 or 3 next to number of ‘Number of ACT scores you wish to report’???

Since all your colleges will receive all 3 ACT test dates, you might as well report 3 on Common App to be consistent.
