The number of the world's wild tigers has dropped to almost 3% of what it was 100 years ago. As few as 3,200 exist in the wild today, mostly in India. Which of these imposes the greatest selective pressure on the wild tiger population? A. Increased genetic variation B. Increased interactions with humans C. Increased prey availability D. Increased reproductive success

The correct answer is B. Increased interactions with humans.<br /><br />Increased interactions with humans impose the greatest selective pressure on the wild tiger population. Human activities such as habitat destruction, poaching, and human-tiger conflict have led to a significant decline in the tiger population. These activities directly affect the survival and reproduction of tigers, making them the primary selective pressure on the population.
