Which of the following statements about anomalous expansion of water are correct? i. There is contraction between 0^oC and 4^oC. ii. There is expansion between 0^oC and 100^oC. iii. The volume is minimum at 4^oC. iv. The volume is maximum at 4^oC

Here is an explanation:

Between 0-4oC,water behaves strangely such that it's volume decreases as its temp increases {the molecules of water which are frozen(expansion) are broken down by extra heat} and therefore has a minimum volume & max density @4oC.
