Three statements are given below followed by four inferences.
Statements:

1. All rivers are pond.
2. Some waterfalls are ponds.
3. All ponds are oceans,
Inferences :

(I) Some waterfalls are rivers.
(II) Some waterfalls are oceans.
(III) No ocean is waterfall.
(IV) All ponds are rivers.
Choose most appropriate option. ​​​​

1. All rivers are pond.
2. Some waterfalls are ponds.
3. All ponds are oceans.

Inferences:

(I) Some waterfalls are rivers.
No direct link between waterfalls and rivers → cannot conclude

(II) Some waterfalls are oceans.
Since some waterfalls are ponds and all ponds are oceans → definitely true

(III) No ocean is waterfall.
We already know some waterfalls are oceans → this is false

(IV) All ponds are rivers 
Given is Rivers ⊆ Ponds, reverse not valid

So, Only inference (II) follows

Final Answer:
