Explanation

Choice A is correct. It’s given that $t equals 4 u$ . Multiplying both sides of this equation by 2 yields $2 t equals, 2 times, 4 u$ , or $2 t equals 8 u$ .

Choice B is incorrect and may result from dividing, instead of multiplying, the right-hand side of the equation by 2. Choices C and D are incorrect and may result from calculation errors.
