Task: Answer the multiple-choice question.
Question: Which drug has a 5.324\% 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 additional words.
Options:
a.) CCO[C@H]1OC(C(=O)N2CCCCCCC2)=C[C@@H](c2csc3ccccc23)[C@@H]1CCCO
b.) O=C(CSc1nc2[nH]ncc2c(=O)[nH]1)Nc1cccc([N+](=O)[O-])c1
c.) CCNCC(O)COCC(O)CNCC
d.) COc1cccc(NC(=O)N2CCCC2C(=O)NC23CC4CC(CC(C4)C2)C3)c1
Answer: a. CCO[C@H]1OC(C(=O)N2CCCCCCC2)=C[C@@H](c2csc3ccccc23)[C@@H]1CCCO
