option B 120 degree is right ans.
bz total angles in watch in a complete circle is 360°
so 360/12 = 30 °
now calculate difference between numbers .
given time 8:20
so we will get number 8 and 4
so diff 8-4= 4
now multiply diff = 4x30°= 120°
and other angle which it makes is 360-120= 240 which isn't given in options

The answer is option (b) 120°
GIVEN
Time 8.20 o'clock
TO FIND
What is the angle between the two hands at 8.20 o'clock?
SOLUTION
We can simply solve the above problem as follows;
We know that,
60 minutes = 360°
Angle between 1 minute = 360/60 = 6°
Minutes minutes between the two hands at 8:20 O'clock = 20
Angle between 20 minutes = 20 × 6 = 120°
Hence, The answer is 120°
