Should B1 be 3 or 4 (3 is a lot more tricky)?

I am trying to count various numbers and letters in multiple cells that
are
seperated by commas.

Example

a1 = 1,4
b1 = 3,89,3,16
c1 = 3a,4,7

I only want to count the number of unique entries in each cell (meaning a1
would result in 2, b1 would result in 4, and c1 would result in 3, etc.)

Is there a way to do this?

Please help. Thank you.
