Ms Deepika conducted a few experiments to explain the properties of metals and non-metals. She set up the experiments as shown in the given figure.
She noted her observations as :
I. No reaction will take place in beakers (iv) and (v).
II. H2 gas will be evolved in beakers (i), (ii) and (iii).
III. A vigorous reaction will take place in beaker (i) while no reaction will occur in beaker (ii).
IV. Two different gases will be evolved in beaker (iv).
The correct observations are
AII, III, and IV only
BII and IV only
CI and III only
DII and III only.
