Final Answer :
C
Explanation :
The fifth rule of validity states that if the conclusion is particular, then one premise must be particular. This is only relevant if we adopt the modern view of existential import, which means that we recognize the existence of things named by terms that are particular (i.e. referring to specific individuals). This rule is important because it ensures that the argument is not making an invalid assumption about the existence of certain individuals.
