In "orphans give indian couple will to live," the paramesvarans refuse to accept more children into their home because
a the government will not allow it
b they believe the other children's parents are still alive
c they want to make sure they have enough resources to care for the ones there now
d they are from a neighboring village which has a long standing dispute with their villages

I believe you refer to the article in Washington Times from December 30, 2005.

I this article, we find this quote

“I don’t want to bite off more than I can chew. If I take more children into this home, I shall not be able to provide them as much support as I want,” said Mr. Paramesvaran.

I interpret this to mean that C. they want to make sure they have enough resources to care for the ones there now
