Calculation of Standard Error of the Mean:
- Standard Error of the Mean (SEM) is calculated by dividing the standard deviation by the square root of the sample size.
- The formula for SEM is: SEM = standard deviation / √(sample size)

Given Data:
- Standard deviation = 20
- Sample size = 100

Calculation:
- SEM = 20 / √100
- SEM = 20 / 10
- SEM = 2
Therefore, the standard error of the mean is 2. Hence, the correct option is (a) 2.
