The character table of $\mathrm{C}_{2 \mathrm{v}}$ point group is given below. In cis-butadiene molecule the vibrational modes belonging to $\mathrm{A}_{2}$ irreducible representation are IR inactive. The remaining IR active modes are

(a)$7 \mathrm{A}_{1}+5 \mathrm{B}_{1}+8 \mathrm{B}_{2}$

(b)$9 A_{1}+4 B_{1}+7 B_{2}$

(c)$7 \mathrm{A}_{1}+3 \mathrm{B}_{1}+7 \mathrm{B}_{2}$

(d)$9 \mathrm{A}_{1}+3 \mathrm{B}_{1}+8 \mathrm{B}_{2}$
