A. 1
B. 2
C. 3
D. 4

Answer 1

Correct Answer - D
`underset("(1-aminobutane)")(CH_(3)-CH_(2)-CH_(2)-CH_(2)-NH_(2))`
`{:(CH_(3)-CH_(2)-CH-CH_(3)),(" |"),(" "underset("(2-aminobutane)")(NH_(2))):}`
`{:(" "CH_(3)),(" |"),(CH_(3)-C-CH_(3)),(" |"),(underset("(2-Methyl-2-aminopropane)")(NH_(2))):}`
`{:(overset(3)(C)H_(3)-overset(2)(C)H-overset(1)(C)H_(2)-NH_(2)),(" |"),(underset("(2-Methyl-1-aminopropane)")(CH_(3))):}`
