Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.420\% 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.) O=S(=O)(NCCCN1CCOCC1)c1ccc2c(c1)OCCO2
b.) O=C(NC1CCCC1)C(c1cccnc1)N(C(=O)c1csnn1)C1CCCC1
c.) Clc1cccc(-c2nnc(-c3ccno3)o2)c1
d.) O=C(COc1ccc2c3c(c(=O)oc2c1)CCC3)NCCCN1CCOCC1
Answer: a. O=S(=O)(NCCCN1CCOCC1)c1ccc2c(c1)OCCO2
