Correct answer: B. Afternoonअपराह्न
Explanation
Ground-level ozone is a secondary pollutant formed by photochemical reactions of NOx and VOCs (from morning traffic) in sunlight. Sunlight is strongest around midday, so ozone peaks in the afternoon and falls at night.धरातलीय ओज़ोन एक द्वितीयक प्रदूषक है जो सूर्य के प्रकाश में NOx और VOC (सुबह के यातायात से) की प्रकाश-रासायनिक अभिक्रियाओं से बनता है। दोपहर के आसपास सूर्य का प्रकाश सबसे तीव्र होता है, अतः ओज़ोन अपराह्न में अधिकतम होती है और रात में घट जाती है।More People, Development and Environment questions
