Options

A. `"FCH"_(2)"COOH" gt "ClCH"_(2) "COOH" gt "BrCH"_(2) "COOH"gt CH_(3)`COOH
B. `CH_(3)`COOH`gt "BrCH"_(2) "COOH" gt "ClCH"_(2) "COOH" gt FCH_(2) `COOH
C. `FCH_(2)"COOH" gt CH_(3)"COOH" gt "BrCH"_(2)"COOH" gt "ClCH"_(2)`COOH
D. `"BrCH"_(2) "COOH" gt "ClCH"_(2) "COOH" gt FCH_(2) "COOH" gt CH_(3)`COOH
