                                    Answer- A - The diagnosis for an individual presenting with chest discomfort, dyspnoea, fatigue, pressure in epigastrium and palpitations, as well as a recent history of viral flu, is Myocarditis.  A viral cause is common for Myocarditis, where non-specific changes in an ECG and a lab culture with a growth of influenza virus are also indicated.
