Task: Answer the MCQ question.
Question: Which drug has a -4.048\% 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) CCn1c(SCC(=O)NNC(=O)c2ccc(C)cc2)nnc1-c1ccncc1
(b) O=P(c1ccccc1)(c1ccccc1)c1nc2ccccc2s1
(c) COc1cc(OC)cc(-c2nnc(NC(=O)Cc3ccc(F)cc3)o2)c1
(d) COCCNC(=O)/C(C#N)=C/c1c(N2CCCCCC2)nc2c(C)cccn2c1=O
Answer: b. O=P(c1ccccc1)(c1ccccc1)c1nc2ccccc2s1
