Answer:
A). A Fraud in the execution.
Explanation:
'Fraud in the execution' or 'fraud in the factum' is demonstrated as the misrepresentation that leads a party to enter a contract without assessing or realizing the potential risks, obligations, or duties associated with it.
As per the question, option A i.e. 'fraud in the execution' that could not reach the core or interior of the contract because this involves misrepresentation or artifice that compels a party to enter the contract but such misrepresentations only exist at the execution level and not at the core of it. Therefore, option A is the correct answer.
