All India Bar Examination (AIBE) 5-V Previous Year Question Papers with Answers

The correct option is B: In-curable.

This is because patent ambiguity in interpreting documents renders it void and cannot be explained by extrinsic evidence. Patent ambiguity refers to the uncertainty or defect on the face of the document, which makes its meaning unclear or unintelligible. According to Section 93 of the Indian Evidence Act, 1872, no evidence can be given to explain or amend an ambiguous document when the language of the document on its face appears to be ambiguous or defective. Therefore, patent ambiguity is incurable and renders the document invalid.

The other options are incorrect because they do not match with the legal definition and effect of patent ambiguity. Option A is wrong because patent ambiguity is not curable by any external evidence. Option C is wrong because patent ambiguity is always incurable and does not depend on any other factor. Option D is wrong because it does not offer any alternative answer.
