The most appropriate reagent will be option A TsCl, Et3N. Treatment of alcohol with tosyl chloride (TsCl) in presence of base will produce the given sulfonate ester. A base is required for this reaction and triethyl amine is the base here which is supplied to neutralize the produced HCl as side product. This is a substitution reaction where O-H bond substituted by O-S bond and Et3N will speed up the forward reaction by HCl neutralization.
