  • B: The S enantiomer of Ibuprofen is 100 times more effective than the R form, and Albuterol's R form is the active drug.
  • C: Both Ibuprofen and Albuterol are commonly sold as mixtures of their enantiomers.
  • D: R-Ibuprofen reduces inflammation and pain, while S-Albuterol relaxes bronchial muscles.
