If two spaceships departed from a planet and accelerated away from the planet in opposite directions until reaching 3/4 the speed of light would it be possible for them to send an electromagnetic (light) signal between each other?

I can see two possible answers but am unable to pick between them

1)  The spaceships are moving faster than the speed of light relative to each other and so no signal can be passed between them

2)  A signal could be sent from ship A to the home planet and then retransmitted to ship B, in this situation light would never travel faster than c.
