Task: Answer the MCQ question.
Question: Which drug exhibits a 6.857\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) Br.N=C1c2ccccc2CN1NC(=O)c1ccc(Br)cc1
(b) CCOC(=O)Cc1csc(SCC(=O)/C(C#N)=C(\C)N)n1
(c) Cc1ccc(NC(=O)c2cc(S(=O)(=O)N3CCOCC3)c(Br)s2)cc1
(d) COCCn1c(SCC(=O)NNC(=O)c2ccccc2)nc2ccccc2c1=O
(e) COc1ccc(CC(=O)N/N=C(\C)c2cccs2)cc1
Answer: b. CCOC(=O)Cc1csc(SCC(=O)/C(C#N)=C(\C)N)n1
