Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.556\% 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=C1/C(=C/c2cccs2)CCC/C1=C\c1cccs1.O=S(=O)(O)O
b O=C(NCc1ccc2c(c1)OCO2)c1ccco1
c O=C(CCNC(=O)c1ccco1)Nc1cccc(Br)c1
d COCCn1c(C)cc(C(=O)COC(=O)c2ccc(Br)o2)c1C
Answer: b. O=C(NCc1ccc2c(c1)OCO2)c1ccco1
