Task: Answer the multiple choice question.
Question: Which drug has a 4.246\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCn1cc(C(=O)NCCCOC)c(=O)c2cc(S(=O)(=O)N3CCC(C)CC3)ccc21
(b) COc1ccc(C(=O)Nc2nc3cc4c(cc3s2)OCO4)c(OC)c1
(c) CCOc1ccc(S(=O)(=O)NCCC(=O)Nc2ccncc2)cc1
(d) O=C(Nc1nc(-c2ccccc2)ns1)c1cccs1
Answer: d. O=C(Nc1nc(-c2ccccc2)ns1)c1cccs1
