The Indus Valley civilization was known for its _____.

Check all that apply: I've checked what I think the answers are, but I'm really not sure, Thank you in advance for any help you can offer :)
*sewer system
*temple towers
*streets in a grid of rectangles
water storage systems
pyramids
(What I know(my notes, A bit messy and scattered but might help a bit): The buildings were made of mud and brick, the streets consisted of a grid layout (rectangles), They had sewer systems and open windows, they had toys, They made clay pots and small sculptures, like charms. They were a very cultural civilization. The streets were 32 feet wide. They dug wells. Most sophisticated sewage and drainage system in the ancient world. Water flowed in and out of their homes through pipes. Thick walls. Large houses built around a central courthouse. They had a writing system. The lesson didn't mention anything about temples, but because the question did I looked it up. It seems that there were temples in the Indus valley (or are).
Thanks again :)
