General EnglishGrammar and usage
- AWhile he was digging sand
- Ba large mass fell
- Cand buried him completely
- DNo error
Explanation
The verb phrase 'digging sand' is unidiomatic: one digs 'in the sand' or digs 'the sand', so part (A) carries the error. Parts (B) and (C) — 'a large mass fell' and 'and buried him completely' — are grammatically acceptable on their own. The tested fault is the missing preposition/article after 'digging' in (A). Hence the error is in (A).
