Monomer unit of Novolac is \mathrm{C}_{7} \mathrm{H}_{8} \mathrm{O}_{2} or

molar mass of monomer = 124 g/mol

\mathrm{n\left(\text { monomer) weight }=\text { Novolac }+(n-1) \mathrm{H}_{2} \mathrm{O}\right. \text { weight }}

\mathrm{n \times 124=963+(n-1) \times 18 \Rightarrow n=9}

Hence, the correct answer is 9.
