Concise reasoning:  
• Cardiac prevention guidelines set an LDL-C goal of <100 mg/dL for patients at risk or with established CAD [Beil, 1997, PMID 9303897].  
• The Step-II/NCEP therapeutic diet limits saturated fat to <7 % of total calories to lower LDL-C and reduce coronary risk [Ernst, 1988, PMID 3183260; Schaefer, 1998, PMID 9785062].  
• Numerous cohort studies and meta-analyses show that light-to-moderate alcohol intake (≈30 mL ethanol or ≤2 drinks/day) is associated with a ≈20-30 % reduction in coronary events, largely via HDL elevation and antithrombotic effects [Rimm, 1999, PMID 10591709].  
Because all three targets are endorsed as part of lifestyle/biochemical goals to avoid coronary artery disease, the best choice is “All of the above.”
