Tidal forces are very important to the Algol system today, but were not important when both stars were still on the main sequence. Why not?
A. Main-sequence stars in a system like the Algol system are small compared to their physical separation.
B. Main-sequence stars are too big to be affected by tidal forces.
C. Main-sequence stars are too massive to be affected by tidal forces.
D. Main-sequence stars are unaffected by tidally-induced mass transfer.
