Answer: Regala
Explanation: Regale, regales, doesn’t make any sense cause it’s a past verb. Regalas and regala are pretty much the same with both present verbs but notice that regalas has a ‘s on the end and regala doesn’t. Artesanía has a ‘s’ on the end of the word of the sentence so it will be regala because is one the rules in Spanish grammar, so that you wouldn’t repeat yourself.
I hope this helps :)
