AIIMS 2019 Biology Types of Fruits MCQ Question
Which of the following is incorrect
Mango and coconut are drupe fruit
According to Euro norm IV sulphur content for petrol is 50 ppm
CO₂ and other poisonous gases cause pollution
Apple is a true fruit
Correct Answer
Detailed Explanation
Option D is incorrect because an apple is classified as a pome fruit, not a true fruit. True fruits develop from a single ovary and include types like drupes (e.g., mango and coconut) and berries, while pome fruits, such as apples, develop from a floral structure that includes a fleshy receptacle.
Option A is correct as both mango and coconut are indeed drupe fruits, characterized by a hard stone containing the seed. Option B is also accurate; Euro norm IV specifies that the maximum sulfur content in petrol is 50 ppm (parts per million). Option C is true since CO₂ and other toxic gases contribute significantly to environmental pollution.
