The deputy officer was charged

ERROR IDENTIFICAITON

The deputy officer was charged with looking at over the files to find other evidence of wrongdoing
=> the answer is “B. looking at over” because we should omit “at”. The correct one is “The deputy officer was charged with looking over the files…(without “it”). Am I right? Many thanks.

Yes.

Could you kindly explain more?

[bhaisahab]

'To look at' and 'to look over' are both phrasal verbs with different meanings, you can't mix them in this way, '...looking at over...'

[susiedqq]

But the officer did "look at" the file.

But the officer did "look at" the file.

Yes he did, but to me 'to look over the file' implies something much more thorough than 'to look at the file'.
