Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.070\% 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 CCCSc1cc(=O)n(-c2ccccc2)nc1C(=O)OCC
b c1ccc2c(c1)CNc1ccccc1C2
c O=C(CN1C(=O)/C(=C\c2ccccc2Cl)Oc2ccccc21)NCc1cccnc1
d CCn1nc(CCC(=O)O)c2ccccc2c1=O
Answer: a. CCCSc1cc(=O)n(-c2ccccc2)nc1C(=O)OCC
