Answer:
the variable c is not a integer is no even and not integer
Step-by-step explanation:
I guess the answer is D
(a) if we substitute even values of C in C+6 we find the ans to be even as well as given in the option
Eg.If C=2,4,8
then C+6=8,10,14 respectively and all are even
(b)if we try the same for C-5 when C=8,10,12
C-5=3,5,7 the ans are odd as given in the option.
I have tried my best but please cross check and if u find the ans to be wrong please inform me too in the comments
