Answer 1

The answer to the English question presented above would be letter a. Thinking about it now, I realize that I was wrong. The sentence that does not contain any punctuation errors would be 'Thinking about it now, I realize that I was wrong.'. All the other choices are not applicable.

Answer 2

The sentence that does not contain any punctuation errors is A) Thinking about it now, I realize that I was wrong.
There has to be a comma after now, because the whole order in the sentence is inverted.
