A commercial vehicle with two steered axles and two driving axles is called an 8 × 4 vehicle.

In the 8 × 4 configuration, the first number (8) represents the total number of wheels, and the second number (4) tells us how many of those wheels are powered by the engine (driven wheels).

So, in this case, the vehicle has 8 wheels in total, with 4 of them being driven by the engine (helping the vehicle move), and the other 4 are used for steering (helping to turn the vehicle).

Why the other options are incorrect:

Option A: 4 × 2 means the vehicle has 4 wheels, with 2 of them being driven, and the other 2 being non-driven. This is not what we’re talking about here.

Option B: 2 × 4 means 2 wheels are driven and 4 are steered, which doesn’t match the description.

Option D: 4 × 8 means the vehicle has 4 wheels being driven and 8 steered, which is also incorrect for this scenario.

Therefore, the correct answer is Option C: 8 × 4.
