For an isothermal variable volume batch reactor, the following relation is applicable for a first order irreversible reaction.
XA = k . t
-ln(1 - XA) = kt
εA . ln (1 - XA) = k . t

I think option c is the correct answer.
Reason: from the general batch reactor equation, after deriving the whole equation, it will end up giving you option C as the final form.

C is correct. I too agree.

I agree Option C is correct.
As for first-order reaction in a batch reactor, either it is constant volume or variable volume, the final expression will remain the same as given in option C.

Answer should be C.
Ca=Cao(1-Xa)/(1+Ea.Xa).
The term (1+Ea.Xa) cancels out from both sides when you put Ca value in rate equation for 1st order reaction.
So, integrating we still get -ln(1-Xa)=kt only.
Ca=Cao(1-Xa)/(1+Ea.Xa).

As (-r)=kCa=-dCa/dt.
Where CA=Ca0(1-Xa)/(1+EX).
Where E=epsilon.
And therefore by derivation, we got the Answer C.
Where CA=Ca0(1-Xa)/(1+EX).
Where E=epsilon.
And therefore by derivation, we got the Answer C.

Option B is correct. I agree with @Akshay for reference see page number 69 from octave.
