Money supply is a stock concept, measured at a single point in time, not over a duration, rendering statement (i) inaccurate.
Statement (ii) is incorrect because the government's money holdings are excluded from the money supply.
Statement (iii) is also incorrect as the money supply comprises currency in circulation among the public, not that held by the Central Bank.
Given that all three statements are erroneous, the correct option is (D) (i), (ii), and (iii).
