Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.214\% 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. N=c1sc2ccccc2n1-c1ccccc1
b. O=C1CC[C@H](O)CCN1[C@H](CSc1ccc(Br)cc1)Cc1ccccc1
c. CCS(=O)(=O)c1ncc(Cl)c(C(=O)Nc2ccccc2OC)n1
d. O=c1ccn(CCc2c[nH]c3ccccc23)c2c1CCCC2
Answer: d. O=c1ccn(CCc2c[nH]c3ccccc23)c2c1CCCC2
