Spot the correct spelling of a CSF-shunt procedure.

Option (a) is the correctly spelt word. Correct spelling is: Ventriculoatrial (shunt) a neurosurgical procedure in which cerebrospinal fluid (CSF) is diverted from the brain's ventricles into the right atrium of the heart to treat conditions such as hydrocephalus. (Hindi: वेंट्रिकुलो-एट्रियल शंट) Example: A ventriculoatrial shunt was placed when abdominal placement was not feasible. Explain why other options are incorrect: (b) Ventriculoartial: incorrect letter order; "artial" is not the correct anatomical term. (Hindi: गलत वर्तनी) (c) Ventriculoatriall: extra "l" at the end makes the spelling incorrect. (Hindi: अतिरिक्त अक्षर) (d) Ventriculoateriel: "ateriel" is not related to the anatomical term atrial; spelling and meaning both incorrect. (Hindi: असंबंधित व गलत वर्तनी)
