Once we have assumed a don't care as '1' in SOP we can't use the same don't care for grouping zeros in POS and vice versa. Whether this statement is true or false.

We can.

They are don't cares. We don't care what their value is. When you want 1, assume 1. When you want 0, assume don't care as 0.

Don't Care for them :p
