Task: Answer the multiple-choice question.
Question: Which drug has a 19.183\% 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: COCCCn1c(=O)c2ccccc2n(Cc2ccccc2C)c1=O
b: Cc1ccc2c(c1)sc1nc(=O)ccn12
c: O=C(Cn1c(CO)nc2ccccc21)NCCc1ccccc1
d: COCC(=O)N(Cc1cc2ccc(C)cc2[nH]c1=O)c1ccccc1C
Answer: a. COCCCn1c(=O)c2ccccc2n(Cc2ccccc2C)c1=O
