Solution

The correct option is C i,ii

${C u S O}_{4} .5 H_{2} O d e h y d r a t i o n - -------- \to {C u S O}_{4} + 5 H_{2} O$
$\to$ It we increase the temp, autometically the above decomposition fastens.
$\to$ if humidity is present in the air, ${C u S O}_{4}$ due to it's deliquesent nature absorbs $H_{2} O$ to form ${C u S O}_{4} .5 H_{2} O$ . So, low humidity is to be maintained high temperature, low humidity in air $\to$ favourable dihydroxylation of alkenes with cold, dilute ${K M n O}_{4}$ to give vicinal doils.
Alkynes could not react with cold, dilute ${K M n O}_{4}$ , because ${K M n O}_{4}$ has not got that much oxidizing capacity to oxidize an Alkyne.
