Explanation

Kalsi in Uttarakhand is the northern site of Ashoka's Major Rock Edicts, where all fourteen edicts are engraved. No Ashokan edicts have been found in Kerala, so option (a) is false. Dhauli in Odisha carries the two special Kalinga edicts, but the famous account of the Kalinga war is in Major Rock Edict XIII, which is not engraved at Dhauli, so option (c) is false. Bihar's Minor Rock Edicts are not confined to Pataliputra — Sasaram in Bihar also has one — so option (b) is false.
