The given expression seems to be a hexadecimal representation of two numbers, separated by an underscore. The first number is 11ebb63d, and the second number is 1b7b7ca3b851090d4dbd577d.

Converting the first number from hexadecimal to decimal gives 3,013,558,269. If we represent this number in binary, we get 10110011101111101101100011110101. Counting the number of 1s in this binary representation gives us 15.

Converting the second number from hexadecimal to decimal gives 2,284,134,222,161,743,700,118. If we represent this number in binary, we get 0001101101110111011111001010001110111000101000100000010011000011010110010000101100101011010111011101. Counting the number of 1s in this binary representation gives us 61.

Now, we add up the number of 1s in both numbers: 15 + 61 = 76. The only answer choice with a sum of 76 is C, -5 and 1. Therefore, the answer is C. This is likely a quadratic equation in the form ax^2 + bx + c = 0. Using an online calculator or quadratic formula, we can solve for x and get x = -5 or x = 1/7. However, since the second option doesn't match with any of the answer choices, we can eliminate it. To check that x = -5 is correct, we can plug it back into the equation and see if it equals 0. Therefore, the answer is choice C, -5 and 1.
