Solution

The correct option is B $\frac{3}{5}$
Part of the day spent in doing homework $= \frac{1}{5}$

Part of the day spent in watching football $= \frac{1}{5}$

Part of the day spent in homework and football $= \frac{1}{5} + \frac{1}{5} = \frac{1 + 1}{5} = \frac{2}{5}$

Part of the day left to do other things = One whole day - part of the day spent in homework and football
$= 1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5}$

Part of the day left to do other things $= \frac{3}{5}$
