explain each step please

Below is transition table of NFA If the NFA is converted to equivalent DFA (with transition table TD ), Match the appropriate transitions below for the equivalent DFA. TD({1},a) A. {1,2} TD({1},b) B. {4} C. {1,2,4} TD({1,2},b) D. {2} TD({4},a) E. {3,4} TD({1,2},a) F. {2,4} G. H. {1,2,3} I. {2,3}
