Answer:
B. 4
Step-by-step explanation:
So the question is z + 7 = 11 right.
So let us begin, First if you add 3 + 7 that will make 10 which is what we are looking for. Next 4 + 7 will make 11 that is your answer but let us see if there is another same answer. 5 + 7 makes 12 which is close but not the answer. and the last one is 2 + 7 makes 9 which is not even close to the question. So your answer is B. 4 (4 + 7 = 11).
