Johnette,
If I am understanding your question correctly, this refers to subject-verb agreement. I agree with you that “one” is the subject of the sentence. “Of the subjects” is a prepositional phrase. “That is being offered” is a restrictive element that modifies “subjects”. Therefore, “is” in the restrictive element does not agree with “subjects”. Only one of the subjects offered is astronomy, but there are several subjects being offered.
To test the agreement, try inverting the sentence: Of the subjects that is/are being offered, one is astronomy.
Examples:
1. One of the subjects that are being offered is psychology.
2. Of the 10 subjects that are being offered, two are sociology and philosophy.
Hope that this helps!
