Suppose the proposition, please see the picture, please help me to answer it in detail, thank you.

"There are powerful factions to do great things, virtual factions to do practical things, and no powerful factions to do good things" are all hypothetical propositions with sufficient conditions. Only when the current thing is true and the latter thing is false can the whole hypothetical proposition be false. The assumptions in this statement are all correct, that is to say, these hypothetical propositions are all true. Based on their two effective forms of reasoning, an inevitable conclusion can be drawn: 1, and the conclusion of the latter can be affirmed by affirming the former; 2. To deny the latter, the conclusion is to deny the former. There can also be two invalid forms of reasoning, and a probable conclusion (which may be true or false) can be drawn: 1, and the conclusion is negative or positive by negating antecedents; 2. By affirming the latter part, the conclusion of affirming the former part or denying the former part is drawn. There are also two wrong forms of reasoning, which lead to impossible conclusions: 1, by affirming the former and denying the latter; 2. Only by denying the latter can we get the affirmation of the former.

A, there is no right not to do good, but it is impossible to draw a conclusion that the former denies the latter;

B, it is a probable (possible) conclusion to deny the former and the latter by not doing practical things without virtual work;

C, have the right to do good, and "have the real power to do great things" is not contradictory, "great things" can also be a good thing, this reasoning is also effective, belonging to the former, draw a conclusion to affirm the latter;

D, no real power, don't do great things, deny the former and deny the latter. It is also a probable (possible) conclusion.

Therefore, the least likely to be deduced from a known statement is a.
