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
