Question

Because I am very interested in the position you have available at your company, would like to schedule an interview with you.

Answer 1

The answer to your question is b

Answer 2

In my persepctive i'd like to believe its B. It seems to be not talking in the way of a true job interveiw. Also there is gramarr mistakes which is what the option B suggests


For example a better way of saying this would be-
Due to me being  interested in the position you have available at your company, I would like to schedule an interview with you whenever you have time. 

Also the way they started it off proves its inccorect in grammar
... After careful thinking I believe you should go with B. It has more proof and confirmation from 2 other users:)

HOPE THIS HELPS
