Given:

$\begin{gathered} \Delta ABC\cong\Delta DEF \\ \angle A=50 \\ \angle E=30 \end{gathered}$

To find:

$\angle C$

Since,

$\begin{gathered} \Delta ABC\cong\Delta DEF \\ \angle A=\angle D=50 \\ \angle B=\angle E=30 \\ \angle C=\angle F \end{gathered}$

Using the angle sum property, we get

$\begin{gathered} A+B+C=180 \\ 50+30+C=180 \\ C=180-80 \\ C=100 \end{gathered}$

Hence, the correct option is C.
