From the text, it is clear that water distribution was often conditional and involved agreements such as leasing, hiring, or sharing in exchange for a share of agricultural produce. This implies the use of a barter-like system, confirming option (b). Moreover, in the absence of a private owner, responsibility for maintenance could shift to either charitable individuals or the community (village), validating option (c).
Why other options are incorrect:
(a) While the text talks about usage and maintenance, it doesn’t explicitly state how the sharing was implemented (like via channels or structures).
(d) The water-works were not free; there was an expectation of return, such as a share of produce.
