Choice B is correct. Subtracting 61 from each side of the given equation yields  |p| = 4. By the definition of absolute value, if |p|  = 4, then p = 4 or p = -4. Of the given choices, 4 is a solution to the given equation.
Choice A is incorrect. This is the quotient, not the difference, of 65 and 61. Choice C is incorrect. This is the sum, not the difference, of 65 and 61. Choice D is incorrect and may result from conceptual or calculation errors.
