Because punnet squares are based off probability.
If we're talking about the pregnancy-morning-pain-relief smear, it's an exogenous hazard.
Out of those ones, im sure its c. It's definitely not b or d. It allows motion but also protects vital organs. :)

Answer:
4.31 × 10²
Explanation:
Equation of the reaction;
⇌ 
The ICE Table is shown as follows:
⇌ 
Initial 3.10 2.50 0
Change - x -x + 2x
Equilibrium (3.10 - x) 0.0800 2x
From
;
We can see that 2.50 - x = 0.0800
So; we can solve for x;
x = 2.50 - 0.0800
x = 2.42
which = (3.10 -x) will be :
= 3.10 - 2.42
= 0.68
= 2x
= 2 (2.42)
= 4.84
