Check whether the following timed automaton will ever reach the state $c$ at $5$ seconds of starting from

state a$.$

a$.$ Yes

b$.$ No

Given the above timed automata expressed as $($:$L,L_0,L_{\text{a}\text{c}\text{c}},,,E$:$)$ find out $$ and $$

a$.=\{a,b,c\},=\{x,y\}$

b$.=\{(x2),(y2)\},=\{reset\{y\}\}$

c$.=\{\},=\{x,y\}$

d$.=\{x,y\},=\{\}$
