Provide an appropriate response.According to data collected during one year in a large metropolitan community, 30% of commuters used public transportation to get to work, and this rose by 4% the following year. This is modeled by the transition matrix 
M = 
S0 = [0.3 0.7]where P represents the percentage of people that use public transportation and P' the percentage of people that do not. What percentage of commuters in this community will use public
transportation in the long run? A. 37.2% B. 30% C. 34% D. 50%
