Question Analysis

This question involves the concept of intersecting lines within the context of a 3D figure. The main focus is on applying the definition of intersecting lines to determine which pairs of lines intersect in the given triangular prism.

Key Concept Explanation:

Intersecting lines are defined as coplanar lines that cross each other at a single point.

Option Analysis

The correct answer is C. The intersecting lines are AB and KA. They share a common point A, fulfilling the definition of intersecting lines where two lines cross at a single point.

The other options are incorrect:

Option A: AB is parallel to KL because AB and KL are opposite sides of the base and are coplanar and do not intersect.

Option B: EA is skew to LM...
