This is called a dynamic race hazard.<\/p>\n<p>In a sequential circuit, the output is determined by the inputs and the state of the circuit. The state of the circuit is determined by the previous inputs and outputs. If the inputs change at different times, the state of the circuit may change depending on the order in which the changes occur. This can also lead to a dynamic race hazard.<\/p>\n<p>To avoid dynamic race hazards, it is important to design circuits so that the inputs change at the same time. This can be done by using synchronizers to ensure that the inputs are stable before they are used in the circuit.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Combinational circuits only. This is incorrect because dynamic race hazards can also occur in sequential circuits.<\/li>\n<li>Option B: Sequential circuits only. This is incorrect because dynamic race hazards can also occur in combinational circuits.<\/li>\n<li>Option C: Both combinational and sequential circuits. This is the correct answer because dynamic race hazards can occur in both types of circuits.<\/li>\n<li>Option D: None of the combinational and sequential circuits. This is incorrect because dynamic race hazards can occur in both types of circuits.<\/li>\n<li>Option E: None of the above.
