Which effect results when exceeding compressor surge limit?

💡 Explanation

Surge causes reversed flow due to insufficient pressure rise against downstream pressure. This unstable operation occurs because the pressure ratio is too low to sustain flow; therefore, option A is correct, rather than increased efficiency or optimized pressure recovery where the normal pressure profile is preserved.
