C) 0, 3
D) 3, 3

The output of a neuron is determined by its inputs and the weights of those inputs. In this case, the neuron has two inputs and a threshold value of 2, which means that the neuron will produce an output of 1 if the sum of its inputs*weights is greater than or equal to 2, and an output of 0 if the sum is less than 2. 
To produce an output of 0 only when both inputs are 0, the sum of the weights times the inputs must be less than 2 when both inputs are 0. Therefore, we want the weights of both inputs to be less than 1, so that the sum of both inputs times their weights is less than 2 when both inputs are 0. 
Choice D) 3, 3 satisfies this condition, as 0*3 + 0*3 = 0 is less than 2, but any other combination of weights would produce an output of 1 when both inputs are 0.
