Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 16.052\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCOC(=O)CN1C(=O)N[C@@H](c2cccs2)C(C(C)=O)=C1C
(b) CN(C)c1ccc(P(=O)(Nc2ccccc2)N2CCOCC2)c(NC(=O)c2cccs2)c1
(c) Cc1cccc(C)c1NC(=S)NNc1ncc(C(F)(F)F)cc1Cl
(d) Cc1ccc(NC(=O)c2cccc3c2-c2ccccc2C3=O)cc1C
Answer: a. CCOC(=O)CN1C(=O)N[C@@H](c2cccs2)C(C(C)=O)=C1C
