A few comments on this one
1. Most sim instructors (in the US) use RT that would make your average ATC weep. As such, I've seen them give very confusing clearances that have led to the student botching the manoeuvre.
2. Without knowing if your company has any VS limits below certain altitudes, I can't say that option A is wrong. The altitudes on the charts are typically minimum, and not mandatory altitudes. Crossing the FAF at 2500 isn't my preferred technique, but it's not objectively wrong.
3. My preferred technique would be option B, if staying at 2500. Just start down a 3 degree path early.
