Answer 2

Answer:

the answer is a.

Step-by-step explanation:

Commutative property : The subtraction of whole numbers is not commutative, that is, if c and d are two whole numbers, then in general c–d is not equal to (d–c).Verification:We know that 9–5=4 but 5–9=−4 which is not a whole number. Thus, for two whole numbers c and d if c>d, then c–d is a whole number but d–c is not possible and if d>c, then d–c is a whole number but c–d is not possible.Now, if c=d=3 then, c−d=3−3=0 which is also a whole number.Hence, whole numbers are commutative under subtraction if and only if c=d.
