Question

The net resistance of an ammeter should be small to ensure that (A) it does not get overheated (B) it does not draw excessive current (C) it can measure large currents (D) it does not appreciably change the current to be measured

Ammeter are designed to have a small internal resistor in order to measure the current passing on its branch without actually using any of it. Usually, it has a negligible internal resistance and voltage drop which is ideal to use for measurement approximations.
