I am assuming that the balanced equation is
2H₂ + O₂ ⇒ 2H₂O
Since the hydrogen is the limiting reagent (meaning if the hydrogen runs out the reaction stops), we need to compare the mole ratio between hydrogen and water.
The mole ratio between H₂ and H₂O is 2:2, or 1:1 (as seen on the coefficients of the balanced equation)
And so for every mole of hydrogen, it will be equal to water. Since hydrogen is 4 moles, 4 moles of water would be created.
So we use the coefficients of H₂ and H₂O in order to answer this question.

Explanation:-
- Ovaries are the the primary female reproductive organs.
- There are two ovaries which are located on either side of the uterus.
- The two functions of ovaries are -i) to produce eggs (ova) and ii) to produce female hormones.
Answer:
A

Because it will not cause much harm to the environment.
I hope it's right (best of luck).
