Task: Answer the MCQ question.
Question: Which drug has a 4.740\% human ether-à-go-go related gene (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 CCOC(=O)c1cnc(SCC(=O)c2ccc(C)cc2)nc1N
b O=C1C(c2ccncc2)=C(O)c2ccccc21
c CCOC(=O)CCNC(C(=O)OCC)c1ccccc1
d O=C(CCc1nnc(CCc2ccccc2)o1)NC[C@H]1C[C@H]2C=C[C@H]1C21CC1
Answer: d. O=C(CCc1nnc(CCc2ccccc2)o1)NC[C@H]1C[C@H]2C=C[C@H]1C21CC1
