#' @title Put Rho
#' @description Calculate the Rho (Option Greek) of Option Contract
#' @param s Spot Price of Underlying Asset
#' @param k Exercise Price of Contract
#' @param t Time to Expiration
#' @param sd Volatality
#' @param r Risk free rate of return
#' @param d Divident Yield (use cont.rate()), Default: 0
#' @return Output gives the Estimated Premium of a Option Contract.
#' @details Rho represents the rate of change between an option's value and a 1% change in the interest rate.
