Solution

The correct option is B A, C and D
Bases when added to acidic solutions, such as sulphuric acid, undergo a neutralisation reaction to give neutral solutions containing salt and water as the products. The pH of neutral solutions is 7.
Antacid, baking soda and glass cleaner are basic in nature and can neutralise sulphuric acid. Water is neutral and cannot neutralise the acid.

Thus, the correct option is b.
