If A represents total number of solid elements and B
represents total number of liquid elements, then the
ratio A:B is
(1) 1:2
(2) 3:2
(3) 2:3
(4) 2:1​

Answer 1

Total no of solid elements(A)=4

Namely iodine, sodium, zinc, carbon

Total liquid elements(B) =2

Namely mercury and bromine

So A:B is

4:2 i.e. 2:1 ratio

Answer 2

Answer:2:3

Explanation:iodine solid element are sodium and zinc but liquid elements are iodine bromine Mercury
