Task: Answer the MCQ question.
Query: Which drug exhibits a 12.450\% 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, d, or e without using any other words.
Options:
a O=C1CN(C(=O)CSc2nncs2)c2ccccc2N1
b CC1Cc2ccccc2N1C(=O)CSc1ncccc1C(=O)O
c Clc1ccc(OCCCn2ccnc2)c(Br)c1.O=C(O)C(=O)O
d CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)C(C)SCC(=O)Nc2ccc(C)cc2)cc1
e O=C(O)CCCN=C1NC2(CCCC2)Cc2ccccc21
Answer: a. O=C1CN(C(=O)CSc2nncs2)c2ccccc2N1
