$\begin{array}{l}\text{ Here, }\\ \Rightarrow \hspace{0.17em}(2^3{)}^{1.1}\times (2^2{)}^{2.7}\times 2^{3.3}=2^{?}\\ \\ \Rightarrow 2^{3\times 1.1}\times 2^{2\times 2.7}\times 2^{3.3}=2^{?}\\ \\ \Rightarrow 2^{3.3+5.4+3.3}=2^{?}\\ \\ \Rightarrow 2^{12}=2^{?}\\ \\ \Rightarrow ?=12\end{array}$

Hence, Option E is correct.
