Answer

Brief Explanations:

When the air - hole of a Bunsen burner is open, there is sufficient oxygen for complete combustion. Complete combustion produces a non - luminous blue cone flame which is hotter and used for heating. A luminous yellow flame forms when the air - hole is closed due to incomplete combustion. A safety flame is not the type of flame described here.

Answer:

A. Non - luminous blue cone flame
