Assertion (A): The amino acid glycine predominatly exists in the form of `^(o+)NH_(3)CH_(2)COO^(Theta)`.
Reason (R) : The conjugate acid of glycine is `NH_(2)CH_(2)COO^(Theta)`.

Options

A. If both (A) and (R) are correc, and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct but (R) is not the correct explanation of (A).

D. If (A) is incorrect, but (R) is correct.

Answer

C

Explanation

`(A)` is correct. It exists as Zwitter ion…
`(R)` is wrong. The conjugate acid is `overset(o+)NH_(2)CH_(2)COOH`
