How do I write this formula?

If column B contains column A value, return value in column C.

Example:

Column A Column B Column C
1026 BLACKHAW ST 1022 Blackhaw St Friendswood, MD. 03079-1002 ##
835 WYCLIFFE DR 1026 Blackhaw St Friendswood, MD. 03079-1002 SS
618 WOODBEND LN 1100 Blackhaw St Friendswood, MD. 03079-1003 QQ
FOREST DR 1102 Blackhaw St Friendswood, MD. 03079-1003 WW
PEBBLEBROOK DR 1106 Blackhaw St Friendswood, MD. 03079-1003 QQ
Carolcrest 847 Wycliffe Dr Friendswood, MD. 03079-3511 AA
CHADBOURNE DR 843 Wycliffe Dr Friendswood, MD. 03079-3511 QQ
Britoak 839 Wycliffe Dr Friendswood, MD. 03079-3511 AA

sorry, it's scrambled.

I really need help.

actually this won't work, because column A value doesn't exact match column B.

A1: 123 main street
A2: 256 main

B1: 256 main dr Maryland
B2: 456 Washington DR Maryland
B3: 123 main street Maryland

C1: QQ
C2: WW
C3: $$


So in this example, since B1 contains A2 value; B3 contains A1 value, I need to D2 return value to be C1, D1 return value to be N/A, D3 return value to be $$

Does this make sense?
