Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.911\% 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) O=C(COC(=O)C1CCN(c2ccc(C(F)(F)F)cn2)CC1)NCc1ccccc1
(b) CCCc1[nH]n(-c2ccc([N+](=O)[O-])cc2)c(=O)c1C=NCCc1ccc(OC)c(OC)c1
(c) CCCc1cc(=O)oc2cc(OC(=O)CN3C(=O)NC4(CCCC4)C3=O)ccc12
(d) CC(C)COC(=O)CCn1[nH]c(=O)c2ccccc2c1=O
Answer: c. CCCc1cc(=O)oc2cc(OC(=O)CN3C(=O)NC4(CCCC4)C3=O)ccc12
