Which of the following would increase the effect of tides on Earth (high tides get higher, low tides get lower)

- slowing the rate of rotation of the Moon.
- increasing the rate of rotation of the Moon. ***
- decreasing the distance between the Earth around the Sun
- increasing the rate of revolution of the Earth around the sun.
I'm really stuck on this one

The moon faces the earth and we only see one side from here. It is stuck rotating 360 degrees every day. Rotation is spinning on your own axis. Changing its rotation rate would not change tides.

decreasing distance between earth and sun would effect the height of full moon and new moon tides.
changing the length of a year by increasing the rate of revolution would be quite something but any effect on tides would be dwarfed by the change of all other characteristics of our orbit.
