Got a question about enforcement--

Third down for Team A on their 30 yard line when A1 throws a pass to A8 who is ineligible reciever. A8 catches the ball (a)behind the line at the 25 yard line and advances for an apparent TD; (b) beyond the line at the 35 yard line and advances for an apparent TD.

Question--
in (a) is the penalty enforced from the 25 yard line since it was behind the line of scrimmage (basic spot)?
in (b) is the penalty enforced from the previous spot which was the 30 yard line?
and carries 5 yards and loss of down?
