grammar - Using "not only but also"

Here is a question I got:

Will the correct answer be

"Not only does Earth Day deserve a commemoration, but also our total dedication."

or

"Earth Day deserves not only a commemoration, but also our total dedication."?

Answer

"Earth Day deserves not only a commemoration, but also our total dedication."

This is correct here, since is perfectly maintains the parallelism. However, you have to remove the comma.

"Not only does Earth Day deserve a commemoration, but also our total dedication."

This breaks the parallelism, so it is incorrect. A better alternative would be "Not only does Earth Day deserve a commemoration, it deserves our total dedication".
