Answer #1

21. Silane , borane and white phosphorus is highly pyrophoric. So, correct option is : (b) methane

22. I am sure that statement (c) is right. Statement (b) is also correct because it can also oxidise some organic solvents such as benzene.

So, correct option is indeed : (d) b and c

You already marked the correct option.
