The correct answer is D. P01 Ã P10 = 1.
The Time Reversibility Test is a test that is used to determine whether a process is reversible. A reversible process is one that can be reversed without any change to the system. The Time Reversibility Test states that if the product of the probabilities of the forward and reverse processes is equal to 1, then the process is reversible.
In the case of the question, the forward process is the process of going from state 0 to state 1, and the reverse process is the process of going from state 1 to state 0. The probability of the forward process is P01, and the probability of the reverse process is P10. The Time Reversibility Test states that if P01 Ã P10 = 1, then the process is reversible.
In this case, P01 Ã P10 = 1, so the process is reversible.
Option A is incorrect because P01 Ã P10 is not equal to 100.
Option B is incorrect because P01 Ã P10 is not less than 100.
Option C is incorrect because P01 Ã P10 is not greater than 1002.
