The Police is looking ____ the mother. (১৮তম শিক্ষক নিবন্ধন স্কুল: ২০২৪)

The correct answer is option (a) "into." The phrasal verb 'look into' means to investigate or inquire about something. Here the police are investigating the (case of the) mother. ✗ 'Look after' = to take care of. ✗ 'Look at' = to observe. ✗ 'Look on' = to watch passively. Note: If the sentence meant caring for the mother, 'looking after' would be used. Source: Oxford Phrasal Verbs Dictionary.
