Answer 1

The correct option is C Both conclusions I and II follows

Mediate term of the following statement is
1. All railways are trains (A - type)
No train is a station (E - type)
A + E $\to$ E - type
No railway is a station
Conclusion II follows
2. No train is a station (E - type)
Some station are platform (I - type)
$E+I\to O_R-type$
Some platform are not trains
3. No railway is a station (E - type)
Some stations are platform (I - type)
$E+I\to O_R-type$
Some platform are not railways

Both conclusions I and II follow.
