Best answer

According to the given data, we can draw the Venn diagram as shown below and all conditions given are satisfied. (We can also draw Venn diagram differently like taking Bed and Bench as same set, but this is just one possibility)

None of the given statement can be inferred according to the Venn diagram. (If any statement can be inferred it must hold true for any Venn diagram)

So, Correct answer is $(D)$

What would be wrong if I put lamp in between bed and bulb means lamp is intersecting bed from left side and intersecting bulb from right side $?$


Okay. I got it. See if my reasoning is correct

We can make both possibilities but in order to dis-satisfy (one case) both $i)$ $ii)$ your figure would be helpful.
