She noted the observation as:
(I) No reaction will take place in beakers (iv) and (v).
(II) Hydrogen gas will be evolved in beakers in (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:
- II, III and IV only
- I and III only
- II and III only
- II and IV only
