Which of the following inertial reference frames are proper frames for the two events listed? Choose all that apply.

RED FRAME: Event A happened at a different place than event $B.$

ORANGE FRAME: Event C happened at $(-3m,-8m,-3m)$ and event D happened at $(-3m,-8m,-3m).$

YELLOW FRAME: The distance between where event $E$ occurred and where event $F$ occurred was $0$ m $.$

GREEN FRAME: A rocket was traveling at a constant velocity when it passed through a stationary tunnel. Event $G$ was the front of the rocket entering the tunnel and event $H$ was the the front of the rocket leaving the tunnel.

BLUE FRAME: A stationary rocket was engulfed by a hollow cylinder that was moving at a constant velocity. Event J was the front of the rocket entering the cylinder and event K was the the front of the rocket leaving the cylinder.
