Answer:
A. {4,20}
Step-by-step explanation:
First we should know what a complement is. The complement of set N in set M refers to the elements that are in set M but not in set N.
Write out the sets:
M = {4, 16, 20, 29}
N = {16, 29}.
To find the complement of N in M, identify the elements in M that are not in N.
16 and 29 are in both set N and M. However, 4 and 20 are in set M but not in set N.
Thus, the complement would be {4,20}
