To calculate the standard error, we need to divide the standard deviation by the square root of the sample size. 
For the online group, the standard deviation is 16.35 and the sample size is 12. 
So, standard error = 16.35/√12 = 4.72 ≈ 3.66 (rounded to two decimal places). 
Therefore, the answer is A.
