Answer:
Option B, temperature, water and soil nutrients
Explanation:
Abiotic factors are those which do not have life in them and are unable to exhibit the functions of a living organism such as locomotion, reproduction, feeding, respiration etc.
All the set of factors in option B i.e temperature, water and soil nutrients are not living things as they do have any of the characteristics of living beings and thus they can be considered as abiotic factors.
