Task: Answer the multiple choice question.
Question: Which drug has a -3.670\% 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 other words.
Options:
a) O=C1CC(c2nc3ccccc3[nH]2)CN1c1ccccc1F
b) CCc1ccc(C(=O)COC(=O)c2cc([N+](=O)[O-])ccc2NCCO)cc1
c) Cc1cccnc1NC(=S)Nc1ncccc1C
d) CCOC(=O)N1CCN(Cc2nc(N)nc(Nc3ccccc3C)n2)CC1
Answer: a. O=C1CC(c2nc3ccccc3[nH]2)CN1c1ccccc1F
