b

Explanation:

MASS can't change You mixed them in the same beaker and they are two clear solutions so not a,c,d but it is B

BYE

Explanation:

I am not sure without knowing the name of the solutions. But according to me it can be happen which are D bcz when two solutions for e.g acid and base are mixed together, it changes its colour an form salts.
