Option A = it dies
Explanation:
Homeostasis:
It is the ability of organisms to maintain the equilibrium in its internal environment in order to deal with external environmental changes.
If the unicellular organism cannot maintain the homeostasis it would die.
Importance of homeostasis:
It is constant chemical and physical condition of cell. The unicellular organisms in maintained homeostasis condition can grow and reproduce. They respond to the environment and transfer energy. It is the primary objective of unicellular organism other wise they would not survive.

Answer is 0.10 mol.
<em>Explanation;</em>
n = m/M
Where n is number of moles (mol), m is the mass of substance (g) and M is the molar mass of the substance (g/mol).
n = ?
m = 0.40 g
M = 4.0 g/mol
From substitution,
n = 0.40 g /4.0 g/mol
n = 0.10 mol
Hence, the balloon has 0.10 mol of He.
