Statement
The cotton crop continues to be poor even after the introduction of improved variety of cotton seeds.
Assumptions
I. The yield of cotton was expected to increased after introduction of improved variety of seeds.
II. The yield of cotton was adequate before the introduction of new variety of seeds.

 The alphabets are coded as shown :

$$\begin{gathered} R O S ? E C H A I P \\ 6 8 2 1 7 3 4 5 9 \end{gathered}$$

So, in SEARCH,

S ia coded as 2,
E as 1,
A as 4,
R as 6,
C as 7,
H as 3.
Thus, the code for SEARCH is 214673

If each consecutive letter in "happiness" relates to the consecutive numbers in 517768399, then H=5, A=1, P=7, I=6, N=8, E=3 and S=9.

Using the numbers that relate to the letters in 'senipah', you will arrive at

SENIPAH = 9386715.

Hence, Happiness is to 517768399 as senipah is to 9386715.

 The alphabets in the given words are coded as follows :

$$\begin{gathered} M ? I ? S ? T ? A ? K ? E N D \\ 9 7 6 5 4 1 2 8 3 \end{gathered}$$

D is coded as 3,

I as 7,
S as 6,
T as 5,
A as 4  and
N as 8.
So, the code for DISTANT is 3765485.

Only option b will be apt among all the statements above
