C can't be the answer, it's D. this is because as the available concentration of the compound decreases the volume of gas given off will continue to increase to a certain point where there won't be any noticeable increase in volume.
all the best,

In a real-world scenario, the curve would likely resemble a combination of Y and R.
It would start with a relatively steep slope, indicating a rapid increase in oxygen production.
Then, it would gradually flatten out, approaching a horizontal line as the reaction reaches completion.
The product increases not diminish!!! Till the reactant is finished

This question needs to be corrected!
Option A is correct
we are dealing with rate of chemical reaction here?
which means R= 1/T
from the relationship, u will see that rate decreases with time.... meaning the graph we are to choose should be inverse..
And those saying the answer is D are confusing the question with concentration in electrochemical cell...
Because in chemical reaction concentration increases with increase in reaction.....
