More appropriate adjectives for 'cries' would be 'loud', 'frequent', 'numerous', or 'incessant'. The phrase 'prolific cries' is not standard English usage, making this part erroneous.\nB. (II) orphaned children moved everybody: This part is grammatically correct. 'Orphaned children' is a valid noun phrase, and 'moved everybody' is a correct verb phrase with its object.\nC. (III) present at the funeral.: This part is grammatically correct. 'Present at the funeral' acts as a participial phrase modifying 'everybody'.\nD. (IV) no error: Since there is an idiomatic error in part (I), this option is incorrect.
