Answer:
Option B 
Step-by-step explanation:
Both plants and animals can reproduce asexually, therefore option A is incorrect 
Organisms that reproduce sexually have the advantage to produce genetically diverse offspring. Hence, option C is incorrect 
Heterotrophs can reproduce both sexually and asexually, hence there is not no relation between being heterotroph and reproducing either asexually or sexually. Hence option D is also incorrect 
If an organism reproduces asexually, then there is no pressure on it to select its mate. Hence, option B is correct
