The correct options are:

Step-by-step explanation:

Joint Frequency--

The entries that are present in common of two conditions i.e. the number of times the combination of two conditions comes.

Marginal Frequencies--

The entries that are present in the total row or total of column entries are called marginal frequencies.

From the table we could see that the entries in the pink box are joint frequency and in the blue columns are  marginal frequency.

Hence,

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
