Question

The restriction on n, k and p so that PY + WY will be defined are:
A. k = 3, p = n
B. k is arbitrary, p = 2
C. p is arbitrary, k = 3
D. k = 2, p = 3

Answer 1

Answer:

Order of W=n×3

Order of Y=3×k

Thus, order of PY=p×k, when k=3.

And the order of WY=p×k, where p=n

Thus option (A) is correct.
