Using Ohm's Law, we can solve for resistance by dividing voltage by current: R = V/I. However, we are not given the voltage. Instead, we can use the power formula: P = IV = I^2*R, where P is power in watts. Rearranging this formula, we get R = P/I^2. We are given the power in the form of the code "11eb8aea_0730_2cfc_8952_190bd8314410_TB8846_00", but this is not helpful information. Therefore, we cannot solve for resistance directly. However, we can use the answer choices and the fact that the current is 1.5 A to estimate which resistance value is most likely. Looking at the answer choices, B and D are the closest to each other in value, but D is significantly higher than B. Therefore, we can eliminate D. Then, calculating the power using P = IV, we get P = (1.5 A)*(8.0 Ω) = 12 W, which matches the power value in answer choice B. Therefore, the best choice is B (8.0 Ω).
