Conclusion: MARRIAGE causes GOOD HEALTH.

The assumption is WHAT MUST BE TRUE for this conclusion to be valid.
Apply the NEGATION TEST.
When the correct answer choice is negated, the conclusion will be invalidated.
D, negated:
Single people with health problems are LESS LIKELY TO GET MARRIED than are other single people.
Implication:
ONLY HEALTHY PEOPLE are likely get married.
The negation of D invalidates the conclusion: if most married people were healthy BEFORE they got married, the argument cannot conclude that marriage causes good health.
Since the negation of D invalidates the conclusion, D is the correct ASSUMPTION: what must be true for the conclusion to be valid.

The correct answer is D.

I agree with Letter "D"

Your health and overall attitude have a lot to do with whether your marriage is pleasant or not.
