Note:
From Question number's 21 to 30 rules for Answer marking.
If the Questions have options then you have to answer as follows 
If your answer is option 3 Then fill the OMR sheet as ‘3’
If your answer is options 2&4, Then fill the OMR sheet as ‘24’
if you answer is options 1,3&4 then fill the OMR sheet as ‘134’
And if you answer is options 1,2,3&4 then fill the OMR sheet as ‘1234’
If the question is numerical based, then fill the OMR sheet as usual.
 

The adjoining figure shown the variation of photocurrent with anode potential for a photosensitive surface for three different radiations . Let $n_{a,}{n}_{b}and{n}_c$ be the number of incident photons per unit area and  time, $f_{a,}{f}_{b}and{f}_c$ be the frequencies of incident light, ${\lambda }_a,{\lambda }_{b}and{\lambda }_c$  are the de-Broglie matter wave length of fastest photo electrons for the curves a,b and c respectively

	Column I		Column II
A	$\frac{n_a}{n_b}$	p	1
B	$\frac{{\lambda }_a}{{\lambda }_c}$	q	<1
C	$\frac{f_a}{f_b}$	r	>1

Now, match the column I with Column II and choose the correct options from the codes gives below 
1) A matches with p          2) B matches with r
3) C matches with p          4) A matches with q
