Complete step by step solution:
Phenobarbitone, also known as Phenobarbital, is a drug of the barbiturate type. It is recommended by the WHO for the treatment of certain types of epilepsy diseases. It is commonly used for seizures in young children. It is occasionally used to treat anxiety.
Structure of phenobarbitone is:


Phenobarbitone was brought to the market in 1921 by a drug company named as Baeyer, with the trade name ‘Luminal’. It works by controlling the abnormal electrical activity in the human brain that occurs during a seizure. This medicine is also used for a short time to give calm or help you sleep during periods of anxiety. It generally works by affecting different parts of the human brain to cause calming or relaxing. Its dosage is based on your medical condition and phenobarbitol blood levels. Withdrawal from phenobarbitone or luminal can be severe and rarely leads to death. Though it may help people in calming, its medication may sometimes cause addiction to the users.

Thus, luminal is the other name of phenobarbitone. Therefore, option B is correct.

Note: A misspelling of the drug luminal is luminal which is commonly used in forensics. Phenobarbitone with trade/brand name luminal is an anti-epileptic drug, for a disease called epilepsy. Epilepsy is a result of genetic disorder or an acquired brain injury, such as trauma or stroke.
