An IF function with 4 outcomes

Hi guys, I am sort of stuck with an IF function so I need your help.

My column D is filled with different three-digit numbers that don't go in any particular order.

So if the value of D is 235 or 244 or 307 - I need the function to write A (there is actually much more numbers that go into the condition, but you get the point)
If the value of D is 330 or 331 or 333 or 340 or 341 or 379 or 380 or 709 or 714 - I need the function to write B
If the value of D is 342 or 370 or 375 or 455 - I need the function to write C
And if the value of D is any other number, I want the function to leave a blank space.

So that's it, I hope I explained it right. Let me know if you need any additional info.

Thanks! :D

Worked like a charm! Thank you abubaniyan!
