Mismatched premises and conclusion. (B) presents a valid conditional chain (Working Properly→Not Blurry→Properly Exposed and Properly Developed), with a conjunction in the necessary condition. It then reaches the valid conditional conclusion that the sufficient condition leads to both necessary conditions. The stimulus, however, presents a conditional chain with a disjunction in the necessary condition, and concludes that the absence of one necessary condition leads to either the remaining necessary condition or the absence of the sufficient condition.

Mismatched premises and conclusion. (C) presents a single conditional statement (Not Working Properly→Blurred or Dark). It then validly concludes that the absence of both necessary conditions implies the absence of the sufficient condition. The stimulus, however, presents two conditional statements in a chain, so (C) doesn’t match.

Mismatched premises and conclusion. (D) presents a conditional chain with a disjunction in the middle variable. It then validly concludes that the sufficient condition leads to the last necessary condition. The conclusion, however, features a conditional chain with a disjunction in the last necessary condition, and concludes that the absence of one necessary condition leads to either the remaining necessary condition or the absence of the sufficient condition.

Mismatched premises and conclusion. (E) presents a valid conditional chain (Work Properly→Properly Exposed→Enough Light and Not Too Much Light), with a conjunction in the necessary condition. It then reaches the valid conditional conclusion that the absence of either necessary condition leads to the absence of the sufficient condition. The stimulus, however, presents a conditional chain with a disjunction in the necessary condition, and concludes that the absence of one necessary condition leads to either the remaining necessary condition or the absence of the sufficient condition.
