The number of avian species in this sanctuary [have decreased] significantly due to the rapid loss of natural habitat and climate change.

Answer और ExplanationAnswer and explanation

Answer: (D) has decreased

The number of subject (कर्ता) है, और कारण habitat loss है।
Concept: The number of + plural noun (बहुवचन संज्ञा) + singular verb (एकवचन क्रिया)। Habitat loss का अर्थ भी कमी है, बढ़त नहीं।
✓

'are increasing' species से agree करता है, परंतु subject number है।
सरल अर्थ: इस अभयारण्य में पक्षियों की प्रजातियों की संख्या प्राकृतिक आवासों के तेज़ी से नष्ट होने और जलवायु परिवर्तन के कारण काफ़ी घट गई है।
The number of is the subject, and the cause is loss of habitat.
Concept: The number of + plural noun + singular verb. Habitat loss also means a decrease, not an increase.

'are increasing' agrees with species, but the subject is the number.

बाकी Options उत्तर क्यों नहीं हैंWhy the other options are not the answer

Aबहुवचन 'species' से 'are increasing' मेल खाता लगा। परंतु कर्ता एकवचन 'number' है, और आवास की हानि कमी की ओर संकेत करती है, वृद्धि की ओर नहीं।'are increasing' agrees with the plural 'species'; but the subject is the singular 'number', and habitat loss points to a decrease, not an increase.
B'species' से 'were increasing' मेल खाता और भूतकालिक प्रतीत हुआ। परंतु कर्ता एकवचन 'number' है, और दिए गए कारण कमी बताते हैं।'were increasing' agrees with 'species' and sounds past; but the subject is the singular 'number', and the causes given mean a decrease.
C'having increased' सहज participle (कृदंत) रूप लगा। परंतु यह वाक्य की मुख्य क्रिया नहीं बन सकता, और 'increased' आवास-हानि के अर्थ के विपरीत है।'having increased' is a smooth participle form; but it cannot act as the main verb of the sentence, and 'increased' contradicts the meaning of habitat loss.
