For a neuron to produce an output of 1 only when both inputs are 1, we want its activation function to be similar to the AND gate. In an artificial neural network, connections weights represent the strengths of the influence of the input neurons on the output neuron. So, the neuron will produce an output of 1 only if the sum of inputs multiplied by their corresponding weights are greater than or equal to the threshold value. 
In this case, we want the threshold value to be 3 and the inputs to have a weight of 2 each, so that only when both inputs are 1, their sum (2+2=4) will be greater than the threshold (3) and the neuron will produce an output of 1. Thus, the correct choice is D (2,2).
