• B. inflammable

Answer 1

• The substances which have very low ignition temperature and can easily catch fire with a flame are called inflammable substances.
• Inflammable substances: Inflammable substances are those substances that catch fire very easily and their ignition temperature is very low.
• Examples of inflammable substances are alcohol, petrol, liquefied petroleum gas and so forth. Inflammable substances are the ones that are much harder to burn or catch fire.
• Hydrogen gas is a highly inflammable gas and it has very less molecular weight.
• Kerosene also has low ignition temperature and it is inflammable.
• Methane is also an inflammable substance, and methane is also called natural gas.
• Hence the correct answer to be filled in the blank will be ignition and inflammable.
