Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct place to click on any of the double peak showing between 2500 and 3000 $cm^{-1}$ on the uploaded question

Explanation:

The group which is being highlighted is an Aldehyde functional group denoted by this structure ( $=C-H$ )

This groups stretch on the infrared spectrometer gives two medium intensities peaks

Its stretch comes at 2820 - 2850 $cm^{-1}$ peak 1

and at 2720 - 2750 $cm^{-1}$ peak 2

So the correct click would be on any of the two peaks between 2500 - 3000 $cm^{-1}$ region
