You Answered:

Selection CNon-anginal chest pain

Reasonable, but there is a better choice

The correct answer is: (B).

Choosing this category would be reasonable, although atypical angina is probably the best category. In non-anginal pain, the pain does not have the characteristics of angina, which our patient's pain does have. The pain's substernal location fits the definition of angina, although it does not radiate and is described as an ache, rather than as squeezing, pressure, or heavy. Non-anginal pain is usually not related to exertion.
