The correct answer is B. 16 Ohms.
A speaker is an electroacoustic transducer that converts an electrical signal into a mechanical vibration, which in turn creates sound waves. The resistance of a speaker is the opposition to the flow of current through it. The resistance of a speaker is typically measured in ohms.
The resistance of a speaker is determined by its design and construction. The main factors that affect the resistance of a speaker are the size and shape of the speaker cone, the material of the speaker cone, and the number of turns of wire in the speaker coil.
The resistance of a speaker is important because it affects the amount of power that the speaker can handle. A speaker with a higher resistance can handle more power than a speaker with a lower resistance.
When testing a speaker, it is important to measure the resistance of the speaker to make sure that it is within the specified range. If the resistance of the speaker is outside of the specified range, then the speaker may be damaged or defective.
The other options are incorrect because they are not realistic values for the resistance of a speaker.
