Generic Engine inputting the data of fuel consumption

I am working with

Generic Engine: Internal combustion engine with throttle and rotational inertia and time lag

Library: Simscape / Driveline / Engines & Motors

I am trying to match the fuel consumption data from the datasheet with the Engine block. The data sheet is attached below. But there are four options in the fuel consumption model.

1-Constant per revolution

2-Fuel consumption by speed and torque

3-Brake-specific fuel consumption by speed and torque

4-Brake specific fuel consumption by speed and brake mean effective pressure

1- What is the best option to use?

2- How to enter the fuel consumption data of the selected engine in the engine block?
