Option D (2nd table in the second row)
Step-by-step explanation:
a = b + 8.6
From the options given, the relationship between a and b should be:
b = a + 8.6
This is because the values of b in all the tables are more than the values of a. Also if we follow this relatioship, we would be able to get the correct answer in the option.
b = a + 8.6
a) if a = 2
b = 2 + 8.6 = 10.6
10. 6 is different from 17.2 (option is wrong)
b) if a = 2
b = 2 + 8.6 = 10.6
10. 6 is different from 8.8 (option is wrong)
c) if a = 2
b = 2 + 8.6 = 10.6
This is correct with the value of b. we need to confirm if other values on the same table follow this
if a = 4
b = 4 + 8.6 = 12.6
12.6 is different from 10.8 as value of b
d) if a = 2
b = 2 + 8.6 = 10.6
if a = 4
b = 4 + 8.6 = 12.6
if a = 6
b = 6 + 8.6 = 14.6
This option is correct as it follows the relationship between a and b
