Question Analysis
This question involves recognizing the defining features of oblique cones.
The main focus is on the orientation of the cone's axis in relation to the base.

Key Concept Explanation
In geometry, the axis of a cone is the segment from the apex to the center of the base.
In a right cone, the axis is perpendicular to the base.
In an oblique cone, the axis is slanted — not perpendicular.

Step-by-Step Solution
Option A: Incorrect. The height and slant height are not necessarily related in this way in oblique cones.
Option B: Incorrect. This describes a right cone.
Option C: Correct. This defines an oblique cone.
