The argument structure follows as this structure:
If A , then B
If not A, then not B

Structure in answer choice A. If there is efficiency, there is success. There is efficiency and there will success. IT DOESN'T TALK ABOUT 'NOT' CONDITION

Answer choice B. It also plays the same role as A.

Answer choice C. The confusion is that it tells the structure A bit differently in such way:
There is not B.
If A, then B
So, there is not A
Therefore, we should consider the pattern very carefully.

Answer choice D and E are very similar to each other in a way that both of them doesn't provide a 'NOT' conditions

You have the general idea, but watch the details. The structure of the original argument is this:

If A, then B (To have life, you need water, so any time there is life, there is water.)
NOT B, therefore NOT A (There isn't water on P23, so there isn't life on P23)

Note that this is a VALID argument, not a flawed one. If we know A-->B, we also know NOT B--> NOT A. The argument gives us A-->B and NOT B, and them validly concludes NOT A.

C follows this same logical pattern, despite the difference of order:
Increasing, then buying. But not buying, so not increasing.

A quick way to eliminate A and B is that they are more complex than the original. A sets up TWO conditionals, and then draws an incorrect conclusion from their combination. B's conclusion is valid, but again it's based on combining two different premises. Also, B's premises are not actual conditionals. They are about what MIGHT or MIGHT NOT be true, or what is PROBABLE, so B doesn't match C's focus on what MUST or MUST NOT be true.

D is a flawed argument relying on a classic reversal. Improving--> Increasing. Increasing, therefore Improving. We can't reverse a conditional like that! D would match the valid original if it said "NOT increasing, therefore NOT improving."

E is valid, but just follows the conditional in order. Exp down --> Def up. Exp are down, therefore Def is up. This doesn't rely on negation, so it doesn't have the same structure as the original.

for life > water required
no water > no life

so
A - not efficient > not knowledgeable & xyz > not successful ( too many links, no direct relationship) hence eliminated
B - The relationship is casual and not firm. "might not necessarily be guilty" eliminated
C - to extract oil > drilling machine, no machine > no inc plans (same pattern) : KEEP
D - The relationship is not visa versa, means if real estate price inc doesnt mean town is improving, it could also mean that inflation is high.
E - same , not visa vera, trade deficit increases = export decrease or IMPORT INCREASE. we can say decrease in export > lead to increase in trade deficit but we cant say trade deficit increased means ONLY BECAUSE EXPORT DEC.

SO C
