A)repeating $\hat { \rho } _ { 1 }$

The second iteration of the Cochrane-Orcutt method for AR(1) involves

A) repeating the process in the first iteration for the data adjusted by $\hat { \rho } _ { 1 }$ and $\hat { \rho } _ { 2 }$ .
B) repeating the process in the first iteration for the data adjusted by $\hat { \rho }$ .
C) re-estimating $\hat { \rho }$ following the process in the first iteration.
D) re-estimating $\hat { \rho }$ using the data lagged one period.
