Block Cipher Question

Given the Cipher Block chaining algorithm: Ci-Ex(P, XOR Ci-1) Encrypt the binary message (Po-P4) where the plaintext message is broken into 8 bit blocks using the key (Ex) and the initialization vector (IV) shown. Assume that the Simple Cipher (SC) or encryption is performed in two steps: 1. Invert all the bits in the block. 2. Rotate the inverted bits three bits to the right. The inputs are: Key- 5A Po-9D P1-CA P2-6A P3-1E What is C3? OED 12 14 0 28
