Question 149Electricity & Electronics - Assistant Engineer

The correct answer is D) billion. The multiplier prefix 'giga' (G) represents a factor of 10 to the 9th power, or one billion. This is the standard definition of the 'giga' prefix in the International System of Units (SI), which is widely used for measuring digital storage and data quantities. The other answer choices are incorrect. A) thousand represents the 'kilo' (k) prefix, which is 10 to the 3rd power. B) is not a valid answer. C) 10 to the 6th power corresponds to the 'mega' (M) prefix, not 'giga'.
