The total number of contributing structures showing hyperconjugation (involving $\mathrm{C}-\mathrm{H}$ bonds) for the following carbocation is

Solution

$$ \text { These are total } 6 \alpha-\mathrm{H} \text { to } \mathrm{sp}^2 \text { carbon and they all can participate in hyperconjugation. } $$

Hence, the correct answer is 6.
