**Core Concept**
Pott's disease, also known as tuberculous spondylitis, is a form of tuberculosis that affects the spine, leading to vertebral destruction and potential neurological complications. The infection is caused by Mycobacterium tuberculosis, which primarily affects the intervertebral discs and adjacent vertebrae.

**Why the Correct Answer is Right**
Tuberculosis in Pott's disease involves the vertebral bodies, intervertebral discs, and adjacent soft tissues. The infection spreads through the hematogenous route, where M. tuberculosis bacilli are carried from the primary site of infection to the spine via the bloodstream. The bacilli then infect the endplates of the vertebral bodies, leading to necrosis and destruction of the intervertebral discs.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Pott's disease primarily involves the vertebral bodies and intervertebral discs, not the spinal cord.
**Option B:** This option is incorrect because while M. tuberculosis can infect other parts of the body, Pott's disease specifically refers to tuberculosis of the spine.
**Option C:** This option is incorrect because while tuberculosis can cause abscesses, Pott's disease is characterized by vertebral destruction and disc space narrowing.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that Pott's disease can present with a wide range of symptoms, including back pain, fever, and neurological deficits. A high index of suspicion is necessary for early diagnosis and treatment to prevent long-term sequelae.

**Correct Answer: C. Vertebral bodies, intervertebral discs, and adjacent soft tissues.**
