Anyone kind enough to share how you diagrammed the sufficient and necessary conditions for the prompt and the answer? Correct answer is A.

Parrallel reasoning needs to die.

Stimulus:

S --> M --> UM

UMA --> SA

Answer choice:

D --> M --> L

LT --> DT

BTW, in case you wonder, this is not a mistaken reversal or whatever you call it. It's equivalent to:

S --> M --> UM --> A

Hence, S --> A

and

D --> M --> L --> T
Hence, D --> T
