CENTER ALIGNMENT OF NUMBERS IN SIDE BY SIDE QUESTION DROPDOWN LIST

Hello, Everyone:
Does anyone know? Can anyone share the code I should use to align: center the numbers in a sidexside dropdown list? (Apologies for simplicity of question.) Picture below of list that I'd like to center.) By the way, the question has multiple rows (10). (I do not have access to JavaScript.) I was thinking that I probably will need to add the code to the text of every question. Thank you so much.
