Check: combinational and stored outputs

Distinguish when inputs change from when a register is observed.

Write down when the combinational path and register path update before answering.

For `assign y = a; always_ff @(posedge clk) q <= y;`, change a from 0 to 1 after a rising edge. What happens before the next edge, once the combinational path settles?

Choose an answery becomes 1 and q holds its previously stored value.Both y and q immediately become 1.If declared logic, y also holds until the next edge.The source executes once in written order.
