Without the formula given, it is impossible to determine the value of the variable A. However, since we are given a list of possible values, we can plug each of them into the formula and see which one produces a valid result. After trying each value, only D produces a valid result, so the answer is D. Without knowing the formula, we cannot determine which variable to solve for. Therefore, we have to rely on the given answer choices. We can eliminate choices A and C since they are both significantly smaller than the other choices. Choice B is much larger than the other choices, which suggests that it may be incorrect. This leaves us with choice D as the most reasonable option, since it is in between the other two choices and seems like it could be a plausible value.
