More than one active input to an encoder will often produce an erroneous output. This problem may be partially overcome by the use of:
A) an open- collector NAND gate whose inputs are connected to the decoder's outputs.
B) an additional encoder whose inputs are cascaded to the original decoder's outputs.
C) a priority encoder to ensure that when more than one input is active the output will correspond to the lowest- numbered input.
D) a priority encoder to ensure that when more than one input is active the output will correspond to the highest- numbered input.

A priority encoder resolves conflicts by assigning priority to inputs, and option D ensures the output corresponds to the highest-numbered active input, which is a common approach to handle multiple active inputs.
