Verified By Collegedunia
The Correct Option is D
Solution and Explanation
पद 1: प्रश्न को समझना
हमें natural selection के प्रकारों को पहचानना है।
पद 2: मुख्य सूत्र या दृष्टिकोण
Natural selection के प्रकार:
• Stabilizing selection
• Directional selection
• Disruptive selection
पद 3: विस्तृत व्याख्या
(a) Stabilizing selection सही है।
(b) Genetic drift natural selection का प्रकार नहीं है।
(c) Directional change सही है।
(d) Disruptive selection सही है।
इसलिए सही उत्तर: \[ (a), (c), (d) \] पद 4: अंतिम उत्तर
अतः सही विकल्प (D) है।
