The correct answer is "Since social class is important, Surja is determined to find Tara a respectable wife of the same class."
Explanation: In Chapter IV "Tara Charan" of the book "The Poison Tree", the author explains that "his mother's story was known in Govindpur, no respectable Kaystha consented to give him his daughter" but Surja would not consent him to marry a Kaystha girl of lower class either. Surja felt that Kunda would be a suitable, respectable wife for Tara.
