Answer:

The correct option is C.

Step-by-step explanation:

An angle is called obtuse angle if it is greater than 90° and less than 180°.

A perpendicular lines makes 90° angle on their intersection.

In the given figures,

DB is not perpendicular to AC. From the given it is clear that ∠DBA is less that 90° and ∠DBC is greater than 90° but less than 180° because both angles ∠DBA and ∠DBC are Supplementary angles.

∠DBA is not an obtuse angle.

∠DBC is an obtuse angle.

Therefore the correct option is C.

From the given figures it is clear that the measure of ∠EFH, ∠KLJ and ∠MLK is 90°.

∠MLK is not an obtuse angle.

The measure of ∠GFE is less than 90° because ∠EFH is a complimentry angle.

∠GFE is not an obtuse angle.
