c. Both Y1 & Y2 are correct but Y2 is not a reason for Y1
d. Both Y1 & Y2 are correct but Y2 is definitely a reason of Y1
ANSWER: Y1 only
The statement Y1 is only precise because every signal should not be necessarily even or odd. It can also belong to some other category of signals. Also, the signal which is neither odd nor even odd is basically expressed as the addition (sum) of even and odd signals.
