Task: Answer the multiple choice question.
Question: Which drug has a -1.798\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) Clc1ccc(CN2CCN(c3ncnc4scc(-c5cccs5)c34)CC2)cc1
(b) CCc1nc2c(c(=O)c3ccccc3n2C)c(=O)n1-c1ccc(F)cc1
(c) O=C(CCCCCNc1nc(=S)[nH]c2ccccc12)NCCC1=CCCCC1
(d) CCOC(=O)CCCCCN(Cc1ccccc1)S(=O)(=O)c1ccc([N+](=O)[O-])cc1
(e) O=C(O)c1ccc(NS(=O)(=O)c2ccc(Cl)c(C(=O)Nc3ccccc3[N+](=O)[O-])c2)cc1
Answer: a. Clc1ccc(CN2CCN(c3ncnc4scc(-c5cccs5)c34)CC2)cc1
