Hose identification. Pic attached.

Hey everyone! Had a bothersome issue when I parked last night. Jeep made a sound like air being let out of a tire, smoke was coming from under the hood and into the cab from the ac vents, smelling of coolant. Popped the hood to find a prodigious hole right above the metal clamp on what I believe to be a heater hose. I found a picture online and would like to ask for assistance with identifying it. Thank you in advance for taking the time to read and possibly helping!

Yes, that is a heater hose. Easy and cheap to replace

Yep, just get a couple feet of heater hose at any auto parts house. 3/4" if i remember correctly.
