Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Only conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some javascript are roblox → False (It is possible, but no definite conclusion can be drawn.)
II. Some javascript are minecraft → True (As all javascript are binary, so, all binary are minecraft, so, some javascript are binary is true.)
III. All javascript are minecraft → True (As all javascript are binary, so, all binary are minecraft, so, all javascript are binary is also true.)
