The question as provided is incomplete: it says “The absolute configuration of” but the actual structure/molecule is missing.

To determine an absolute configuration such as $R,R$, $S,S$, $R,S$, or $S,R$, I must have the full stereochemical structure (wedge-dash/Fischer/Newman/etc.) of the compound.

Why the answer cannot be determined from the given data

Absolute configuration depends on:

1. The identity of substituents attached to each stereocenter.
2. CIP priority order at each stereocenter.
3. 3D orientation of the groups (towards/away/in-plane).

Without the structure, none of these can be assigned reliably.

Evaluation of options

Since the molecular structure is absent, the following cannot be justified:

• A: $S,S$
• B: $R,R$
• C: $R,S$
• D: $S,R$

So, from the information supplied, no option can be derived mathematically or chemically.

Comparison with stored correct answer

The stored correct answer is B ($R,R$), but because the actual compound/diagram is missing, I cannot verify that choice.

Hence I must disagree with the stored answer based on insufficient information, not because $R,R$ is necessarily wrong.

What is needed

Please provide the structure/image/name of the compound so I can assign the absolute configuration step-by-step using CIP rules.
