# Which of the following is Nylon-2-nylon-6

$\begin{array}{1 1} a \\ b \\ c \\ d \end{array}$

The numbers 2 and 6 denote the number of carbon atoms present in the main chain of the monomer of the polymers.
$n(H_2N-CH_2-COOH)$ glycine acid,$n(H_2N-(CH_2)_5-COOH)$ amino caproic acid are the monomers of the polyamide copolymer nylon-2,6.
Thus the structure of nylon 2,nylon 6 is
Hence (c) is the correct answer.
