Solution
The correct option is D Oxygen, carbon and phosphorous Solution:- (D) Oxygen, carbon and phosphorous
Oxygen, carbon, phosphorous families are not related to each other as carbon belong to IV B (14th group), oxygen to VI B (16 th group) and phosphorus to VB (15th group) in periodic table, hence, their properties are not related to each other as the elements from different groups exhibit different properties.
