Task: Answer the multiple-choice question.
Question: Which drug has a -1.140\% 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 additional words.
Options:
a CCCCC/C=C/C1=CC(=O)C[C@H](c2ccc(Cl)cc2)C1
b O=S(=O)(c1ccccc1)C1Cc2ccccc2C1Cl
c O=C1CC(N2CCN(c3nc4ccccc4s3)CC2)C(=O)N1Cc1cccs1
d O=C1c2ccccc2C(=O)N1CCN1CCOCC1
Answer: a. CCCCC/C=C/C1=CC(=O)C[C@H](c2ccc(Cl)cc2)C1
