Is the set of rational numbers a group under the operation of addition? If not, why not? Select all that apply.
O A. Yes, it is a group.
O B. No, it is not a group. There is no identity element in the set of rational numbers under the operation of addition.
O C. No, it is not a group. There is at least one rational number that does not have an inverse in the set of rational numbers under the operation of addition.
O D. No, it is not a group. There exist rational numbers a, b, and c such that (a + b) + c a+ (b + c).
O E. No, it is not a group. The set of rational numbers is not closed under the operation of addition.
O F. No, it is not a group. There exist rational numbers a and b such that a + b#b+a.
