The answer is e) Relative risk

Relative risk is the ratio of the incidence of a disorder in those exposed to those unexposed to a suspected risk factor. As such, it indicates how many times greater is the risk in someone exposed versus someone unexposed to the risk factor. This represents strength of the risk factor.
