As you talk in animals
nucleus/ plasma membrane / mitochondria
if you talk in plants
nucleus / the cell / plastid / mitochondria
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!

Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
2 moles of C₂H₆ 6 moles of H₂O
1.4 moles of C₂H₆ x
x = (1.4 x 6) / 2
x = 8.4/2
x = 4.2 moles of H₂O"
