In this question, two statements are given followed by a conclusion. Find out which of the alternatives justifies the given conclusion.
Statements:
1) Oxygen is a gas.
2) Cylinder contains gas.
Conclusion:
Cylinder contains oxygen.

Correct option is D

From the given statement 1 establishes that oxygen exists in a gaseous state.
Statement 2 informs us that a particular cylinder holds some type of gas.
While both statements hold truth, they don't provide absolute certainty that the cylinder specifically contains oxygen. It's a possibility, but other gases could be present as well.
Therefore, the conclusion that the cylinder contains oxygen is likely true, but not guaranteed.
Thus, the conclusion drawn is probably true
