Correct option is A
The correct answer is:
(a) Pusa Surya = Eldon X Amrapali
Explanation:
Pusa Surya: This variety, also known as 'Eldon,' was introduced from Brazil to the Indian Agricultural Research Institute (IARI), New Delhi, in 1981. It is not a hybrid but rather an introduction, and there is no evidence to suggest it is a cross between 'Eldon' and 'Amrapali.
Therefore, option (a) is not correctly matched.
