a) they become slippery when reacting with water
b) they react with metals to release hydrogen gas
c) they produce salts when mixed with other acids

explain please

the answer is B,
For example:
Mg+HCl--->Mgcl2+ H2
Because of the collision theory. THe particle of MG binds with the particle of Cl easily because of their electronegativity.

A and D are obviously wrong, I know in many reactions with metals acids will release hydrogen gas during the procedure, so I'd go with B

b - the best one to choose is magnesium:
Mg + 2HCl ----> MgCl2 + H2
The H+ ions in the acid are reduced by the metal to form hydrogen gas.

b) they react with metals to release hydrogen gas
eg:-
2HCL+Na------->NaCl2 + 2H(gas)
ie hydrochloric acid reacts with sodium metal to give off hydrogen gas
