They are bad people to deal . . . . . . . ., always late in delivery dates. A. into B. in C. upon D. with

into
in
upon
with

The correct answer is D. with.

The preposition “with” is used to indicate a relationship between two or more people or things. In this case, the relationship is between the speaker and the people who are always late in delivery dates. The speaker is saying that these people are bad people to deal with, because they are always late.

The other options are not correct because they do not indicate a relationship between the speaker and the people who are always late in delivery dates.

  • Option A, “into,” is used to indicate a movement into something. In this case, it would not make sense to say that the speaker is moving into the people who are always late in delivery dates.
  • Option B, “in,” is used to indicate a location or position inside something. In this case, it would not make sense to say that the speaker is inside the people who are always late in delivery dates.
  • Option C, “upon,” is used to indicate a position on top of something. In this case, it would not make sense to say that the speaker is on top of the people who are always late in delivery dates.
