The answer would be A
A round character has depth, experiences feelings, emotions, etc. about which the reader is aware. Therefore, a round character is likely to experience internal conflict.
You should chose D. B. would also work, but D. is best. Always put a comma before a name.
The suffix of encoded is "-ed" which shows that it is past tense.
3=c
4=a
5=a
