Which of the following are examples of coordinate headings?

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

My answer was C but i got it wrong,
is it A?
PLEASE HELP CANT FIND IT IN MY TEXT BOOK

the answer is d I just took the test

I would say it's either B or D, but then I don't have your text's definition of 'coordinate.'

Yes, the correct answer is A. "3, b, iii" is an example of coordinate headings. Each element in the heading represents a different coordinate, with the first coordinate being a numeral, the second coordinate being a lowercase letter, and the third coordinate being a Roman numeral. So, in this case, "3" represents the first coordinate, "b" represents the second coordinate, and "iii" represents the third coordinate.

To determine which of the given options are examples of coordinate headings, let's first understand what a coordinate heading is.

Coordinate headings are a way to label different categories or axes in a table, graph, or other visual representation. These headings typically use a combination of letters and numbers or Roman numerals to indicate different levels or dimensions.

Now let's analyze the given options:

A. 3, b, iii - This option uses a mix of numbers and Roman numerals. It could be a coordinate heading, as long as it is used to label different dimensions or levels.

B. A, i, a - This option uses a combination of letters and numbers. Similar to option A, it could be a coordinate heading if it is used for distinguishing different categories or axes.

C. ii, 2, B - This option uses a mix of Roman numerals and numbers, which makes it a strong candidate for a coordinate heading as it follows the pattern often used.

D. A, B, C - This option only contains letters, which is not typical for coordinate headings. It might be more suitable for labeling categories or columns.

Based on the typical usage of coordinate headings, options A, B, and C seem plausible candidates. However, without additional context or information about the specific use case, it is difficult to definitively determine which option is correct.

Therefore, I recommend referring to your textbook or any relevant materials provided by your instructor to understand the specific conventions or guidelines for coordinate headings in your course or assignment. If you still cannot find the answer, reaching out to your teacher or classmates for clarification would be helpful.
