Consider the following DFA

Figure

Which of the following NFA is valid for the given DFA ?

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: D.

Option D

Explanation

The figures in the source paper are too low-resolution to trace every transition reliably. The answer given is the official/PW key; the valid NFA must accept exactly the same strings as the DFA, so check each option by tracing the same input strings through both machines.
