Which of the statements given above is/are correct?
(a) 1 only
(b) 1 and 3

Answer : B

Explanation:

Statement I is correct: Rhynchostylis retusa is an epiphyte growing on tree trunks in open forests or at forest margins at elevations of 300–1,500 m.
Statement II is not correct: The species is found across a wide range of countries including Bhutan, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Philippines, Singapore, Sri Lanka, Thailand, and Vietnam. It is therefore not endemic to North-east India. Within India, it is most common in Northeast, Odisha and Andhra Pradesh.
Statement III is correct: Rhynchostylis retusa is recognized as the State flower of both Arunachal Pradesh and Assam in India.
