As electives, the standard group should be Spanish, Chinese, and Hindi, as these are three most useful languages as a composite of usefulness in business and those using the language in the United States.
Nobody conducts business in Hindi.
Really? I would have thought that it was rather common. I suppose I stand corrected.
This is a common misconception. All educated people in India speak English, and Hindi is only the language of a minority of the population.
A 40%+ minority and a majority language in large parts of northern India. "Nobody" seems a bit hyperbolic.

Just an anecdote, but I once got to sit in on a business meeting between two fluent (not native though) Hindi speakers (my uncle and an investor). For the meeting, thry used English almost exclusively, with a few Hindi phrases thrown in occasionally.
However, at home, my uncle and his family only spoke Punjabi, though they are all fluent in English.
For the question, Nix is correct.
