Observe the following statements : a. The thermal stability of hydrides of group 16 elements follow the order : $\mathrm{H}_2 \mathrm{O}>\mathrm{H}_2 \mathrm{~S}>\mathrm{H}_2 \mathrm{Se}>\mathrm{H}_2 \mathrm{Te}$ b. Acidic nature of hydrides of group 16 elements follow the order : $\mathrm{H}_2 \mathrm{O}>\mathrm{H}_2 \mathrm{~S}>\mathrm{H}_2 \mathrm{Se}>\mathrm{H}_2 \mathrm{Te}$ c. The reducing nature of $\mathrm{H}_2 \mathrm{~S}, \mathrm{H}_2 \mathrm{Se}$ and $\mathrm{H}_2$ Te follow the order : $\mathrm{H}_2 \mathrm{~S} < \mathrm{H}_2 \mathrm{Se} < \mathrm{H}_2 \mathrm{Te}$ The correct statement are:
  1. a, b, c
  2. a,b
  3. b, c
  4. a, c
