A supersonic aircraft has an air intake ramp that can be rotated about the leadingedge O such that the shock from the leading edge meets the cowl lip as shown inthe figure. Select all the correct statement(s) as per oblique shock theory when theflight Mach number M is increased.(A) It is always possible to find a ramp settingRAMP such that the shock still meetsthe cowl lip (SHOCK remains the same).(B) IfRAMP is held fixed, the shock angleSHOCK will increase.(C) If M exceeds a critical value, it would NOT be possible to find a ramp settingRAMPsuch that the shock still meets the cowl lip (SHOCK remains the same).(D) Shock angle1 1sinSHOCK M−     
