The correct option is C The tourism officials of Dubai have closed the newly opened glass elevator due to certain cracks appearing in the structure. These cracks were not considered a threat to safety by the area's management bureau.
(I) and (II) are incorrect because the options suggest that themanagement bureau's statement is true but the paragraph does not comment on its veracity.
(III) is correct because it best captures the essence of the paragraph. It states that a newly opened glass elevator in Dubai has been closed now due to certain cracks that appeared on it. It also covers the part that the area's management bureau has assured later that the cracks do not pose any danger. (IV) is incorrect as it states that the cracks are superficial, which might not be correct. Also, it suggests that the statement of the area management bureau came before the closing of the glass elevator but that cannot be inferred from the paragraph.
