Answer:
Photosynthesis
Explanation:
Process A would most likely be photosynthesis, as during photosynthesis, light energy is absorbed to eventually create glucose and oxygen. These products that result from process A, photosynthesis, are then converted to water and carbon dioxide in process B, which is also known as cellular respiration.

[H+] for HClO(this is a weak acid so it requires an I.C.E. table to solve):
(I=initial amount. C=change in amount. E= amount at equilibrium.)
I.C.E. table
HClO. H2O. >>> H3O+ ClO4-
I. 0.100M. N/A. 0. 0
C. -x. N/A. +x. +x
E. 0.1-x. N/A. x. x.
(we don't consider water because it is not an aqueous solution)
ka=(x^2)/(0.1-x)
(2.9×10^-8)= (x^2)/(0.1-x)
(0.1-x)(2.9×10^-8) = x^2
(3.0×10^-9) - ((2.9×10^-8)x) = x^2
x^2+(2.9×10^-8)x-(3×10^-9)
a=1
b=(2.9×10^-8)
c= -(3×10^-9)
plug those values into the quadratic formula:
x= (-b +(√((b^2)-4ac))))/2a
I got x= 0.000053837
x= [H+] =0.000053837
[H+] for 0.100 M HClO4:
because HClO4 is a strong acid, it dissociates completely. Meaning that it's [H+] =0.1
Radioactivity.
We can watch their radioactive decay to determine their half life.
