The symbol representing a standard deviation calculated by using a sample to estimate the population standard deviation is "s". Option A ("sd") is not a valid symbol. Option B is a mix of F's and the Greek letter sigma and is not a standard symbol for standard deviation. Option D ("SD") is often used as a symbol for standard deviation, but it typically refers to the population standard deviation, which is calculated using all of the data, rather than just a sample.
