### Solution:

It’s given that the following table gives the marks obtained by 60 students in a section test:
Frequency distribution shows frequency (number of students) corresponding to different marks intervals.
In statistics, a frequency distribution which is said to be a list of tables or graphs that display the frequency of various outcomes in a sample.
Now from the table we get,
$F=20+30$
$⇒F=50$
And we know,
$f=58-F$
$⇒F=58-50$
$⇒f=8$
Considering the circumstances stated above, the value of F and f is 50 and 8 respectively.
Therefore, option 3 is correct.
