The given reaction involves substitution of Cl (ligand) with NHS-ester and H2O. This reaction occurs via two mechanisms: cis and trans. In the cis mechanism, Cl and NHS-ester must be adjacent to each other in the complex, whereas, in the trans mechanism, the Cl and NHS-ester must be opposite to each other. The ratio of cis to trans is 4:1 for octahedral complexes when all the ligands are different. However, in the given complex, two of the ligands are the same (S1U1B0), which can result in steric repulsion and make the trans isomer less favorable. Therefore, the ratio of cis to trans isomer will be slightly tilted towards cis, and hence the answer is D (4:1).
