Que.  Let G(x) be the generator polynomial used for CRC checking. What is the condition that should be satisfied by G(x) to detect odd number of bits in error? 
a.  G(x) contains more than two terms 
b.  G(x) does not divide 1+x^k, for any k not exceeding the frame length 
c.  1+x is a factor of G(x) 
d.  G(x) has an odd number of terms 
Answer:1+x is a factor of G(x)
