Metal a reacts slowly with cold water, while metal b reacts vigorously with cold water. metal c does not react with cold water or hot water, but does react with dilute acid. metal d reacts with hot water, but not cold water. the activity series for these metals is: (most reactive to least reactive)
a. b > a > d > c
b. a > b > c > d
c. a > b > d > c
d. b > a > c > d

i think   the answer is c hope i'm right
