Final answer:
To count from 0 to 15 using the IC7493, the Reset 1 and Reset 2 pins should be connected to the ground or logic 0.
Step-by-step explanation:
The IC7493 is a counter circuit that can count from 0 to 15. In order to reset the counter and start counting from 0, the Reset 1 and Reset 2 pins of the IC7493 should be connected to the ground (GND) or logic 0. This will bring the counter to its initial state, causing it to start counting from 0 when clock signals are applied.
