Answer:

B is true

Step-by-step explanation:

A is not correct since a natural number minus another natural number can be a negative, and a negative is not a natural number, therefore natural numbers are not closed under subtraction.

B is correct.

C is wrong because natural numbers are indeed closed under addition.

D is wrong with the same reason as C.
