The correct option is
A if only conclusion I follows.
For situation and conclusion questions, there are two following strategies to follow:
I. Possibility
= There exists at least a Venn diagram to justify the conclusion without violating the situations.
II. Definite
= There must not exist any Venn Diagram that is following the conclusion.( without violating the situations)
In the Venn diagrams, Weak; S= Strong; W= Winners; M= Modest
All weak being modest is a possibility.
According to the strategy I, there is a Venn diagram(1,2) that results in conclusion without violating any of the situations.
So it follows.
No weak is a winner
According to strategy II, there must not exist any Venn diagram but there exists a Venn diagram(2) that is not following the conclusion.
So not follow.
Only conclusion I follows.
Option A
