If x(t) and y(t) are two periodic signals with coefficients Xn and Yn

1.	If x(t) and y(t) are two periodic signals with coefficients Xn and Yn then the linearity is represented as?
A.	ax(t) + by(t) = aXn + bYn
B.	ax (t) + by(t) = Xn + bYn
C.	ax(t) + by(t) = aXn + Yn
D.	ax(t) + by(t) = Xn + Yn
Answer» B.
