EXPERTS!!!!
In Option E,
I am more concerned about the placement of "as children".Had it been placed, for ex - Although they as children always liked playing with toy helicopters,.... - it would have made more sense to use "as".
But here,
isn't it creating confusion by modifying toy helicopters also, by sitting right after it?Yes, not happy with the placement of "as children". It does make the sentence awkward.
But the other options are certainly worse.
In (A), they were not "being" children, not acting like children. They were children.
"while in childhood" and "at the time of their childhood" are both incorrect. Children are not "in" childhood. Childhood is a time period.
Also, since childhood is a time period, it is not a point in time. So use of "at the time" is not correct. The correct usage would be "during childhood".
