BIOLOGYLet p and q be distinct primes: Suppose that H is a proper subset of the integers and H is a group under addition that contains exactly three elements of the set $\left\{p, p+q, p q, p^{q}, q^{p}\right\}$. Determine which of the following are the three elements in H. a. $p q, p^{q}, q^{p}$. b. $p+q, p q, p^{q}$. c. p, p+q, pq. d. $p, p^{q}, q^{p}$, e. $p, p q, p^{q}$
