What Is the Fundamental Matrix for a Markov Process with Absorbing

Multiple Choice

What is the fundamental matrix for a Markov process with absorbing states?

A) A matrix composed of the identity submatrix, a zero submatrix, a submatrix of the transition probabilities between the non-absorbing states and the absorbing states, and a submatrix of transition probabilities between the non-absorbing states.
B) A matrix representing the average number of times the process visits the non-absorbing states.
C) The inverse of the identity matrix minus the matrix of the transition probabilities between the non-absorbing states and the absorbing states.
D) The matrix product of the limiting transition matrix and the matrix of transition probabilities between the non-absorbing states.
