The only motives that influence all human actions arise from self-interest. It is clear, therefore, that self-interest is the chief influence on human action.

A
denies that an observation that a trait is common to all the events in a pattern can contribute to a causal explanation of the pattern
The trait (A) is referencing is self-interest and the pattern is human action, but the author doesn’t say that self-interest can’t contribute to a causal explanation of human action. On the contrary, the author argues that self-interest is the main influence on human action.
B
takes the occurrence of one particular influence on a pattern or class of events as showing that its influence outweighs any other influence on those events
The author argues that simply because self-interest influences motives that influence all human actions, self-interest outweighs any other influences on human actions. The author errs by never addressing how self-interest is the main influence on human actions.
C
concludes that a characteristic of a pattern or class of events at one time is characteristic of similar patterns or classes of events at all times
The author never argues that self-interest influences human actions at some times and, therefore, influences similar patterns or classes of events at all times. He only argues that self-interest is the principal influence on human actions.
D
concludes that, because an influence is the paramount influence on a particular pattern or class of events, that influence is the only influence on that pattern or class of events
The author doesn’t make the case that self-interest is the only influence on human action. He just argues that self-interest is the chief influence on human action.
E
undermines its own premise that a particular attribute is present in all instances of a certain pattern or class of events
The author’s only premise is that motives that influence all human actions come from self-interest. He never undermines this premise.
