## Core Concept
Rheumatic fever is an inflammatory disease that can occur following a Group A streptococcal infection, such as strep throat. It affects various tissues in the body, including the heart, joints, skin, and brain. The major manifestations of rheumatic fever are guided by the Jones criteria.

## Why the Correct Answer is Right
The Jones criteria for rheumatic fever include both major and minor criteria. The major criteria are:
- **Carditis** (inflammation of the heart)
- **Polyarthritis** (inflammation of multiple joints)
- **Sydenham's chorea** (a neurological disorder)
- **Erythema marginatum** (a skin rash)
- **Subcutaneous nodules** (lumps under the skin)

## Why Each Wrong Option is Incorrect
- **Option A:** While not listed, carditis, polyarthritis, Sydenham's chorea, erythema marginatum, and subcutaneous nodules are the classic major manifestations.
- **Option B:** Similarly, these are the major manifestations; the question seems to be missing specifics but implies these are correct major manifestations.
- **Option C:** This option is also a major manifestation; specifics are needed for a direct contradiction.
- **Option D:** **Arthralgia** is actually one of the minor criteria, not a major manifestation.

## Clinical Pearl / High-Yield Fact
A key point to remember is that rheumatic fever's major manifestations can be remembered by the acronym **"CORDS"**: Carditis, O - (omitting to specify but usually), Polyarthritis, Rheumatic (less commonly used), Dermatological (Erythema marginatum), Subcutaneous nodules, and Sydenham's chorea.

## Correct Answer: D. Arthralgia.
