✅ Answer: B) Head Gasket Failure

If a car shows all three symptoms together:

✔ White smoke from the exhaust
✔ Engine overheating
✔ Coolant level continuously dropping

then the most likely cause is a blown head gasket.

Why does this happen?

The head gasket sits between the engine block and cylinder head. Its job is to keep:

* Engine oil separate
* Coolant separate
* Combustion gases sealed inside the cylinders

When the gasket fails:

1. White Smoke from Exhaust

Coolant leaks into the combustion chamber and burns with the fuel-air mixture.

➡ Result: Thick white smoke or steam comes out of the exhaust.

2. Engine Overheating

Coolant escapes from the cooling system, reducing its ability to remove heat.

➡ Result: Engine temperature rises and overheating occurs.

3. Coolant Level Keeps Dropping

The coolant is being burned inside the engine or leaking internally.

➡ Result: You frequently need to top up the coolant reservoir.

Other Signs of a Blown Head Gasket

🔧 Milky white engine oil
🔧 Bubbles in the coolant reservoir
🔧 Loss of engine power
🔧 Rough idling
🔧 Sweet smell from the exhaust

Why Other Options Are Wrong

❌ Battery Problem → Doesn’t cause white exhaust smoke or coolant loss.

❌ Air Filter Choked → May reduce performance but won’t cause coolant loss.

❌ Fuel Pump Issue → Can cause starting or power issues but not overheating and white smoke together.

🎉 Answer Revealed!

The correct answer is B) Head Gasket Failure ✅

Did you get it right?

A blown head gasket can turn a small cooling issue into a major engine repair if ignored. White smoke, overheating, and coolant loss are classic warning signs.
