1 point A combinational logic circuit has one output (F) and four inputs (a, b, c, and d). The circuit is described by the following Boolean expression. A static one hazard occurs when F = (a + b + c)(a +c+d)(b +c+d)(a +c+d) O abcd=1011 changed to 1101 abcd=0010 changed to 0000 abcd=1111 changed to 1001 abcd=0000 changed to 0010 O abcd=1101 changed to 1111 abcd=1010 changed to 0000 abcd=0001 changed to 1010
