MANHATTAN REVIEW OFFICIAL EXPLANATION:

Once again, this question involves a dangling modifier. The first question you should ask yourself is: who are the immigrants? The answer should come after the comma. Only choices B and E are possible. Choice E has an incorrect order of words. ‘Opened’ is too far from ‘Schwartz’s deli’. Choice B is the correct answer.
