Jellyfish ARE made of cells because it is a living creature and that is all the proof you need XD so C is also not true
That leaves you with your answer: D

Answer:
1.36
Explanation:
HClO2 ⇄ H+ + ClO2-
[HClO2] [H+} [ClO2-]
initial: 0.12 0 0
change: -x +x +x
equil: 0.12-x x x
[H+][ClO2-] / [HClO2] = Ka = 1.2 * 10^-2
x* x / 0.12 - x = 1.2 * 10^-2
x^2 = (2.4 * 10^-3) - (1.2 * 10^-2)x
x^2 + (1.2 * 10^-2)x – (2.4 * 10^-3) = 0
Upon solving for x,
x = 0.04335
[H+] = 0.04335
pH = -log[H+]
pH = -log(0.04335) = - (-1.36) = 1.36
