The question image/reaction scheme and the option structures are missing in the provided prompt. Only the text

"In the reaction The product $E$ is :"

is visible, while options $A, B, C, D$ are blank.

Because the actual reaction sequence is not provided, the product $E$ cannot be determined from the available information.

What is needed

To solve this step-by-step, I need:

1. The complete reaction scheme (starting compound and reagents/conditions), and
2. The structures corresponding to options $A, B, C,$ and $D$.

Conclusion

With the present data, it is impossible to derive the correct product independently. Therefore I cannot meaningfully verify whether option $A$ is correct from chemistry reasoning alone.
