The ionic equations represent the reactions between four metals, p, q, r and s, and solutions of the salts of the same metals

p + q2+ -> no reaction
r + p2+ -> r2+ + p
q + s2+ -> q2+ + s
s + p2+ -> s2+ + p
s + r2+ -> s2+ + r
s + q2+ -> no reaction

what is the correct order of reactivity of the metals?

most > least
a. p r s q
b. q r s p
c. q s r p
d. s q p r
