Task: Answer the MCQ question.
Question: Which drug has a 12.503\% 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: CC(C)=CCc1c(O)cc(O)c2c(=O)c(O[C@@H]3O[C@@H](C)[C@H](O)[C@@H](O)[C@H]3O)c(-c3ccc(O)cc3)oc12
b: O=C(CSc1nc2ccccc2o1)N/N=C/c1ccc(C(=O)O)cc1
c: Cc1[nH]nc2c1C(c1ccoc1)C(C#N)=C(N)O2
d: COc1ccc(-c2cc(-c3n[nH]c(=S)n3-c3cc(OC)ccc3OC)[nH]n2)cc1
Answer: a. CC(C)=CCc1c(O)cc(O)c2c(=O)c(O[C@@H]3O[C@@H](C)[C@H](O)[C@@H](O)[C@H]3O)c(-c3ccc(O)cc3)oc12
