Answer: Sentences (i) and (iii) are grammatically correct. The answer is B.

1. Recall the principal parts of 'wake': wake (base) -> woke (simple past) -> woken (past participle). Regular -ed forms 'woked' and 'wokened' do not exist.
2. Evaluate sentence (i): I woke up from sleep: 'Woke' is the correct simple past (active voice). The sentence is grammatically correct.
3. Evaluate sentence (iii): I was woken up from sleep: 'Was woken' is correct passive voice (was + past participle 'woken'). The sentence is grammatically correct.
