Answer

To solve the question "All of the following are tiger subspecies which have recently gone extinct, except," we will analyze each option provided.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are quagga, javan, bali, and caspian.

2. **Research Each Option**:
- **Quagga**: This is not a tiger subspecies. The quagga is actually an extinct subspecies of the plains zebra. Therefore, it does not belong to the tiger family.
- **Javan Tiger**: The Javan tiger (Panthera tigris sondaica) is indeed a subspecies of tiger that is now extinct.
- **Bali Tiger**: The Bali tiger (Panthera tigris balica) is another subspecies of tiger that has gone extinct.
- **Caspian Tiger**: The Caspian tiger (Panthera tigris virgata) is also a subspecies of tiger that is extinct.

3. **Conclusion**: Since the question asks for the option that is not a tiger subspecies, the quagga is the correct answer because it is a zebra, not a tiger.

### Final Answer:
The correct answer is **quagga**.
