Consider the following reactions:

Consider the following reactions:

QCl2(aq) + Z(s) → no reaction

MCl2(aq) + Q(s) → M(s) + QCl2(s)

MCl2(aq) + Z(s) → M(s) + ZCl2(aq)

What is the correct order of increasing activity for the metals M, Q and Z?

A. M < Q < Z              B. M < Z < Q              C. Z < Q < M           D. Z < M < Q
