Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
During thermal decarboxylation of $β$ keto acid, a carbanion intermediate is formed which is resonance stablized. Due to this, the decarboxylation occurs even in absence of sodalime catalyst. Hence, both assertion and reason are correct and the reason is the correct explaination for assertion.
