“Green is matching” is coded as “yj mp nt” ………………..(3)

“Extinct of oral” is coded as “mq vq jb” ……………………..(4)

From (1) and (2), we get:

Problem – ik ………………………………………….(5)

From (1) and (3), we get:

Matching – mp ……………………………………..(6)

From (1) and (4), we get:

Extinct – mq …………………………………………(7)

From (1), (5), (6) and (7), we get:

a – rx ………………………………………………….(8)

From (2) and (3), we get:

is – yj ………………………………………………(9)

From (2), (5) and (9), we get:

Solved – uz ……………………………………..(10)

From (3), (6) and (9), we get:

 Green – nt …………………………….(11)

From (1) and (4), we get:

Of / oral – vq / jb …………………….(12)

So, the code for "Out" is ka.

But 'out' is not given in the solution so the answer is "None of these".

Hence, the correct answer is "option (4)".

In each code, the number = position of the word’s first letter (A1–Z26).

• Distance (D) → 4 ⇒ V4
• Time (T) → 20 ⇒ V20
• Speed (S) → 19 ⇒ W19

In the given code, the number corresponds to the position of the first letter of each word in the English alphabet.

For example, “Distance Time Speed” is coded as “V20 W19 V4”. “Time” starts with ‘T’, the 20th letter, so it is “V20”. “Speed” starts with ‘S’, the 19th letter, so it is “W19”. “Distance” starts with ‘D’, the 4th letter, so it is “V4”.

Therefore, the word that can be coded as “V4” is “Distance”.

SOBER is written as RNADQ.
in RNADQ. every letter is 1 previous of SOBER 
K comes before L
N comes before O
S comes before T
T comes before U
R comes before S

This way KNSTR is correct option

To understand how the word FIRE is converted to HKTG, we analyse the letter shifts:

• F (6) shifts to H (8): +2
• I (9) shifts to K (11): +2
• R (18) shifts to T (20): +2
• E (5) shifts to G (7): +2

Each letter is shifted forward by 2 positions in the alphabet. Now, we apply the same logic to YCVGT:

• Y (25) shifts to A (1): +2 (wrap around)
• C (3) shifts to E (5): +2
• V (22) shifts to X (24): +2
• G (7) shifts to I (9): +2
• T (20) shifts to V (22): +2

So, YCVGT becomes AEXIV.

Move +2,+3,+4 forward for first 3 letters
Move -2,-3,-4 backward for last 3 letters

C +2 = E
A + 3 = D
S + 4 = W
K - 2 = I
E - 3 = B
T - 4 = P

So The answer is EDWIBP

If P means #,A means %,C means $ and E means@
So,
P ⇒ #
E ⇒ @
A ⇒ %
C ⇒ $
E ⇒ @

So the code for PEACE will be #@%$@

From question it is clear that each alphabet has a code based on their alphabetical order. For example a=1, b=2 ....z=26.

by going through options
l ⇒ 12
o ⇒ 15
v ⇒ 22
e ⇒ 5

so code for 1215225 is love.

So, the code for "Out" is ka.

But 'out' is not given in the solution, so the answer is "None of these".

Hence, the correct answer is "option (4)".

The logic followed is here:

And

Similarly, 

Hence, Option d is correct.
