Economic Drain implies a drain on the economy of the country

I have never read economical drain used in the same context but you could say an individual spends his finances economically. To elaborate that to a country is not correct.

B, D, E are eliminated because economical changes the meaning of the sentence.

C is wrong, so debilitating is it (that's a question) .. grammar

A is correct - Although X is not fatal, it is so harmful that it has become an economic drain on the country.
