Identify A and B in the following reaction:

\(A = C_6H_5CH_2NH_2, B = C_6H_5CH_2NH-CH_3) \(A= C_6H_5CH_3, B = C_6H_5CH_2CH_3\) \(A = C_6H_5CH_2NH_2, B = C_6H_5CH_2-N(CH_3)_2\) \(A = C_6H_5CH_2NH_2, C_6H_5CH_2CH_2CH_3\)

\(A = C_6H_5CH_2NH_2, B = C_6H_5CH_2-N(CH_3)_2\)

The correct answer is option 3. \(A = C_6H_5CH_2NH_2, B = C_6H_5CH_2-N(CH_3)_2\)
