Solution

The correct option is C
4:00 pm to 6:00 pm

Current study time duration is 4:00 pm - 8:00 pm
So, he studies for 4 hours currently.
It is given that he used to study two hours lesser before.
$∴$ He used to study for 4 - 2 = 2 hours previously.
So, if he starts studying at 4 pm, then his earlier study plan duration would be 4:00 pm to 06:00 pm.
