Send email after term is selected in checkbox in a node form with rules
You need:


An "Entity has field" condition to check for the existence of the taxonomy field, and then 
A "Data comparison" condition to match the value of the taxonomy field to the one of the three terms on which you want the rule to operate.


You have two Events in your rule. It seems if you put the Field Collection condition first, then the node fields aren't available in Rules, and vice-versa. So list the "After updating existing content of type Online Application Form" event first so that you can access the taxonomy field in the conditions.
