(b) with the consent of the beneficiaries, or with the approval of the court, make leases of the land for such term and on such conditions as the personal representatives may think proper; or

(c) make, on such terms and conditions as the personal representatives may think proper, a sub-lease of the land with a nominal reversion, where such sub-lease amounts in substance to a sale and the personal representatives have satisfied themselves that it is the most appropriate method of disposing of the land in the course of the administration of the estate;
