When considering how a television (TV) operates and the forms of energy involved, we can analyze the options you provided:
1. **Electrical to light and sound**: This is the most accurate description of how a TV operates. A TV converts electrical energy into light (via the screen) and sound (through the speakers).
2. **Electrical to mechanical and sound**: While there may be some mechanical components (like moving parts in older TVs), modern TVs primarily convert electrical energy to light and sound, not significantly to mechanical energy.
3. **Chemical to light to heat**: This option doesn't apply to a standard television. Chemical energy is not a primary source for TVs.
4. **Electrical to heat**: This can be true to some extent, as TVs do generate heat as a byproduct of electrical activity, but it's not the main function of the device.
In summary, the best option describing the primary energy transformations in a television is **"electrical to light and sound."**
