Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.297\% 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=C(NCCNC(=O)c1ccccn1)c1ccc(F)cc1
(b) Cc1ccc(C(NC(=O)c2cccc(S(=O)(=O)N3CCN(C)CC3)c2)c2ccccc2)cc1
(c) CC(Nc1nc(N2CCCCC2)nc2ccccc12)c1ccccc1
(d) CS/C(N)=N/N=C/c1cc(C)ccc1O
Answer: a. O=C(NCCNC(=O)c1ccccn1)c1ccc(F)cc1
