Problem statement: Answer the multiple choice question.
Question: Which drug has a 1.002\% 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(Nc1nc(-c2cccs2)cs1)C1=COCCO1
b C/C(O)=C/c1nc2ccccc2[nH]c1=O
c Cc1ccc(N2C(=O)SC(N(CC(=O)O)c3cccc(C)c3)C2=O)cc1
d CCC1CCCCN1CCCNC(=O)c1ccc2c(c1)c(C)c(C)n2CC
Answer: a. O=C(Nc1nc(-c2cccs2)cs1)C1=COCCO1
