The correct answers about the place of publication in a book reference are:
A. i, ii, iv.
Here’s the breakdown:
i. True - Generally, only the town or city is mentioned in the reference, not the country.
ii. True - If there are multiple places listed, the first two are often included.
iii. False - Typically, the place is given in its English version, especially if the reference style requires it.
iv. True - If the place of publication cannot be traced, "S.I." (sine loco) is used, which means "without place."
So the valid combinations are A.
