Answer:

Option D.)
$100 \textdegree$ is correct.

Explanation:

In a quadrilateral, ABCD, opposite angles are supplementary.

$\angle BCD + \angle BAD = 180\textdegree$

therefore
$\angle BCD = 180\textdegree - \angle BAD = 180\textdegree - 80\textdegree = 100 \textdegree$

therefore option D.)
$100 \textdegree$ is correct.
