**Core Concept**
Urethral injuries can be classified into two main types: anterior (bulbar) and posterior, based on their location and mechanism of injury. These injuries can occur due to various reasons such as straddle injuries, pelvic fractures, or catheterization-related trauma.

**Why the Correct Answer is Right**
The correct answer is related to the classification and management of urethral injuries. Urethral injuries can be further divided into two categories: anterior (bulbar) and posterior, based on their location and mechanism of injury. The anterior urethra is more commonly injured due to straddle injuries or direct trauma, whereas posterior urethral injuries are more commonly associated with pelvic fractures.

**Why Each Wrong Option is Incorrect**
**Option A:** Not applicable, as more information is required to determine the relevance of this option.
**Option B:** This option may be incorrect, but without more context, it's difficult to determine the accuracy of this statement.
**Option C:** This option is incorrect because posterior urethral injuries are often associated with pelvic fractures, not anterior urethral injuries.
**Option D:** This option is incorrect because anterior urethral injuries are more commonly associated with straddle injuries, not posterior urethral injuries.

**Clinical Pearl / High-Yield Fact**
It's essential to classify urethral injuries accurately to determine the appropriate management plan, which may involve surgical repair or catheterization. Anterior urethral injuries are often managed with catheterization, whereas posterior urethral injuries may require surgical repair.

**Correct Answer:** C. Posterior urethral injuries are often associated with pelvic fractures.
