What is wrong with the original statement

[sanjaylakhani]

Well, I also got it worng- I also choose A ...

Parallel structure shld be maintained

[zacharyz]

You can see through parallelism in this case, but that is not really the rule. The original statement is grammatically incorrect in its own right.

To use 'summarizing' you need to be doing it still (Present Participle or Continuous)-
"I am summarizing"... "He is summarizing"... "to be summarizing"

"He does more than merely summarize" is the proper form here.

ex. I do teach. I do exercise. I do watch.
What did you do? teach, exercise, yoga
Present Participle - What are you doing? teaching, exercising, watching
