Question

Consider the following DFA over {a, b, c}

Let X be the language accepted by DFA X. Then which of the following correctly describes X?

Answer 1

$X=L(\ge 1a,\ge 1b,\ge 1c)$
$L(\ge 1a,=0b,\ge 1c)$

$\therefore$ $X=L(\ge 1a,(=0bor\ge 1b),\ge 1c)$

$=L(\ge 1a,\ge 1c,\ge 0b)$ [any number of b's]

Therefore (d) is the correct choice.
