Very interesting question as there are actually three Indian dynasties during the classical period, which includes:
Maurya Dynasty(300-184BCE)
Kushan Dynasty(40-176AD)
Gupta Dynasty(320-550AD)
Gupta is the most influential one but at the same time the youngest. It might not be in the classical period depending on the source of interpretation.
I suggest you check your readings or ask your teacher to determine the span of the classical period.
Hope this helps!
