Consider the fictional reaction: A + B → F + G

which is catalyzed by reagent C. The rate of this reaction was monitored by looking at the disappearance of B under several different experimental setups at 298 K.
Experiment A[M] B[M] C[M] Rate of disappearance of B
1 0.300 0.0500 0.100 0.000107
2 0.400 0.0500 0.200 0.000286
3 0.400 0.0500 0.0500 7.14e-05
4 0.300 0.0500 0.0500 5.36e-05
5 0.300 0.100 0.0500 5.36e-05

Step 1: A + C → D
Step 2: D → E + C
Step 3: E + B → F + G

Given the previous information, which of the following situations would lead to a plausible reaction mechanism?

a. Incorrect Step 2 as the rate determining step. All other steps fast steps.
b. Incorrect Step 3 as the rate determining step. All other steps fast steps.
c. Incorrect Step 3 as the rate determining step. Step 2 is a fast equilibrium step while step 1 is a fast step.
