Generally speaking what is the interpretation of a 95% CI for a population level quantity (mean, proportion incidence rate)

a. The 95% CI will always include the true value of the population level quantity.

b. 95% CIs from larger samples are more likely to include the true value of the population level quantity as compared to 95% CIs from smaller samples.

c. THe 95% CI provides a range of plausible values for the unobserved population level quantity by recognizing the uncertainty in the sample based estimate of this quantity.
