Question:
The passive form of “ They have arrested the thief ” is _____ ?
AThe thief was arrested by them
BThe thief has been arrested by them
CThe thief have been arrested by them
DThe thief had been arrested by them
Answer:
B. The thief has been arrested by them
Explanation:
Active voice ലെ verb 'has + V3' വന്നാൽ passive voice ലേക്ക് മാറ്റുന്ന വിധം: Object + has/have + been + V3 + by + subject. ഇവിടെ active voice ലെ auxiliary verb 'have' ആണ്. ഇവിടെ object 'The thief' ആണ്. The thief (singular) ആയതു കൊണ്ട് തന്നെ auxiliary verb 'has' വരും. അതിനു ശേഷം "been" എഴുതണം. അതിനു ശേഷം arrest ന്റെ V3 form ആയ arrested എഴുതണം. അതിനു ശേഷം by. Active voice ൽ subject ആയി "they" വന്നാൽ passive voice ൽ അത് 'them' ആകും. The reason we use "has" and not "had" is because we're maintaining the same tense as the original sentence.
