To solve this problem, we can use the property of modular arithmetic which states that (a*b*c) mod m = [(a mod m)*(b mod m)*(c mod m)] mod m.

Step 1: Find the remainder of each number when divided by 9.
77 mod 9 = 5
85 mod 9 = 4
73 mod 9 = 1

Step 2: Multiply these remainders together and then find the remainder when the result is divided by 9.
(5*4*1) mod 9 = 20 mod 9 = 2

So, the remainder when 77 x 85 x 73 is divided by 9 is 2. Therefore, the answer is b. 2.
