Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.689\% 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) Cc1cnc(C(=O)N2CCCC(N3CCN(c4ccccc4C)CC3)C2)cn1
b) COc1ccc(NC(=O)c2cccc(N3C(=O)C4C5C=CC(C6CC56)C4C3=O)c2)cc1
c) COc1cccc(CNC(=O)CC2C(=O)NCCN2CCCc2ccccc2)c1
d) CCCCOCCCNC(=O)c1c(-c2ccccc2)noc1C
e) O=C(N/N=C/c1sc(N2CCCCC2)nc1-c1cccs1)C1CC1
Answer: a. Cc1cnc(C(=O)N2CCCC(N3CCN(c4ccccc4C)CC3)C2)cn1
