Task: Answer the multiple choice question.
Query: Which drug has a -0.077\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=c1cc(CO)oc(C(Nc2ccccn2)c2cccc(F)c2)c1O
b. CCN1C(=O)C(O)(C2COC(C)(C)CC2=O)c2cc(Br)ccc21
c. S=C(NCCCN1CCOCC1)N(Cc1ccccc1)Cc1ccccc1
d. O=C(CSCc1cnn(-c2ccccc2)c1-n1cccc1)NCCN1CCOCC1
Answer: b. CCN1C(=O)C(O)(C2COC(C)(C)CC2=O)c2cc(Br)ccc21
