Ans: d
Explanation: Allotropy is a phenomenon in which an element is found in different forms having different physical properties but similar chemical properties is known as allotropy.
The different forms are called the allotropic or simply allotropes.
Phosphorus, sulphur, carbon etc. are elements which occur in different allotropic forms.

Allotropy is a phenomenon in which an element is found in different forms having different chemical properties but similar physical properties. Phosphorus and sulphur are elements which occur in different allotropic forms but Carbon does not.
To understand the correctness of the given statement, let's analyze each part separately.
I. Allotropy is a phenomenon in which an element is found in different forms having different chemical properties but similar physical properties.
This statement is correct. Allotropy refers to the ability of an element to exist in multiple forms, known as allotropes, which have different chemical properties but similar physical properties. Allotropes of an element have different atomic arrangements, resulting in variations in their chemical behavior. However, they may have similar physical properties such as melting point, boiling point, and density.
II. Phosphorus and sulphur are elements which occur in different allotropic forms but Carbon does not.
This statement is incorrect. Carbon is an element that exhibits allotropy. It exists in several allotropic forms, the most common ones being diamond, graphite, and fullerenes. Diamond is a transparent, extremely hard substance, while graphite is a soft, black, and slippery material. Both diamond and graphite are allotropes of carbon with different chemical and physical properties.
On the other hand, phosphorus and sulfur are elements that also exhibit allotropy. Phosphorus can exist in several allotropic forms, including white phosphorus, red phosphorus, and black phosphorus, each with distinct chemical properties. Similarly, sulfur can exist in various allotropic forms, such as rhombic sulfur, monoclinic sulfur, and plastic sulfur.
Therefore, the correct statement should be "I is incorrect but II is correct."
In conclusion, the given statement is incorrect, as carbon is an element that exhibits allotropy, contrary to what is mentioned. Phosphorus and sulfur are also elements that occur in different allotropic forms, supporting the correctness of the second statement.
