Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.264\% 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 additional words.
Options:
a. Cc1ccccc1OCCCC(=O)NCc1ccco1
b. CCOC(=O)/C(C#N)=C/C=C1/C=CC=CN1C
c. C=CCSc1nc2ccccc2n1C(=O)/C=C/c1ccc(OC)c(OC)c1
d. CC1CCN(C(=O)c2ccc(-c3ccccc3Cl)o2)CC1
Answer: c. C=CCSc1nc2ccccc2n1C(=O)/C=C/c1ccc(OC)c(OC)c1
