Answer 1

The correct answer is A and D only.

Key Points The contrary statements among the given options are:

A. All objects are perishable.
D. No objects are perishable.

Explanation:

Contrary statements are those that cannot both be true but can both be false. In this case, statements A and D are contrary to each other because they present opposite views on the perishability of objects.
Statement A asserts that all objects are perishable, implying that there is no object that is exempt from perishing.
In contrast, statement D denies the perishability of all objects, suggesting that there are no objects that are subject to perishing.
Both statements cannot be simultaneously true because they present contradictory claims about the perishability of objects.
However, both statements can be false if there are objects that are both perishable and non-perishable.

Therefore, the correct answer is:

A. All objects are perishable.
D. No objects are perishable.
