Answer:
Somatic mutations : option (A) and option (D).
Inherited mutations : option (B) and option (C).
Explanation:
Mutations are permanent changes in the genetic material due to alterations in DNA sequence. Mutations may be somatic or inherited (or germline).
Somatic mutations are those mutations that arise in somatic or normal body cells and cannot transfer from parents to their offspring. As skins cells and lung cells are somatic cells, option (A) and (D) represent somatic mutations.
Inherited mutations are those mutations that arise in sex cells (gamete forming cell) and transfer from parents to their offspring due to transfer as these cells form mutated gametes. As egg cells and sperms cells are sex cells, option (B) and (C) represent inherited mutations.
Answer:
This scenario has been discovered and studied in slime molds.
Explanation:
The green beard effect is one of the three fundamental mechanisms of kin selection. In the 1960s, W.D. Hamilton in his work on the evolution of altruism brought it into the highlight. The other two mechanisms are kin discrimination and population viscosity. Green-beard effect functions even when the altruist and her recipients are not genealogical kin.

Answer:
São Paulo is a city in Brazil that faced the worst drought in Brazil in the last 100 years between 2014–17.
The reason of the drought was diminished rain falls from last three third consecutive year in the region. Humans were somewhere responsible for the drought and less rainfall because this was caused by expansion of deforestation into the Amazon basin. Deforestation disturbed the environmental cycle that caused less amount of rain in São Paulo, Brazil.
