The moon's synchronous orbit around earth is the direct result of the gravitational relationship between the two, causing a in which one face of the moon is always pointing toward earth.
a) tidal rock
b) solar tide
c) magnetosphere
d) tidal bulge

The answer should be Tidal Lock (A), because this is when the event of the orbital position of an object (Earth) is matching the same rotation period as the other object (Moon). When these rotations are the same, the moon will always be facing the same direction as the Earth. I believe you made a typo because Tidal Rock is not even considered to be a term in science. It is not a Solar Tide (that isn't even concerned with the moon facing the Earth), magnetosphere isn't even related to the moon but its magnetic field, and a tidal "bulge" is the complete opposite and has the moon facing the completely opposite direction.
