Task: Answer the multiple choice question.
Question: Which drug has a 6.474\% 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 other words.
Options:
a.) O=C(Nc1cc2c(cc1Cl)OCCCO2)c1ccco1
b.) Cl.Clc1ccc(CSC2=NCCCN2)cc1Cl
c.) Cc1ccc(S(=O)(=O)c2nc(-c3ccccc3Cl)oc2N(C)C)cc1
d.) CCSc1nc2n(n1)C(c1cccc(F)c1)C1=C(CCCC1=O)N2
Answer: a. O=C(Nc1cc2c(cc1Cl)OCCCO2)c1ccco1
