A)Radio waves are a form of electromagnetic radiation.

TRUE

It is the type of electromagnetic wave with least energy range and longest wavelength range among all

B)Electromagnetic radiation does not require a medium to travel.  

TRUE

This radiation can travel through vacuum also and its speed is maximum in vacuum

C)In a vacuum, electromagnetic radiation travels at the speed of light.

TRUE  

speed of all electromagnetic radiation is same as speed of light in vacuum

D)Electromagnetic radiation travels in the form of longitudinal waves.

FALSE

All electromagnetic radiation is always in form of transverse waves

So correct options are

A, B, C

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
