Question

Which of the following are examples of coordinate headings?

A. 3, b, iii
B.A, B, C
C. A, i, a
D. ii, 2, B​

Answer 1

B. A, B, C

Step-by-step explanation:

Coordinate headings assume using the same type of marking for starting a new chapter. Those can be Arabic or Roman numerals, uppercase and lowercase numerals, cardinal and ordinal numbers, but the author should always use just one of them, not a mixture.

Only in the answer B we find such a marking with using uppercase letters A, B and C.

On the other three answers we have a mixture of Arabic and Roman numerals, uppercase and lowercase letters.
