The following is a Deterministic Finite Automaton $($DFA$)$ for the input alphabet $\{a,b,c\}$ :

What kinds of strings are accepted in this DFA?

Strings in the form of $a^m{b}^n{c}^k$ where $m,n,k0$

Strings in the form of $a^n{b}^{n+1}{c}^{n+2}$ where $n0$

Strings in the form of $a^{n+2}{b}^{n+1}{c}^n$ where $n0$

None of the answers are accepted
