Arshiya has an I.Q. of 135. She is an all-rounder. She not only scores at the top of her class but is also an international chess player and a remarkable beat player as well. Arshiya can be classified as:

The correct option is Gifted.

To understand why this is the correct classification, we can break down the criteria for being classified as "Gifted" in psychology and education:
1. High Intelligence Quotient (I.Q.): Typically, individuals with an I.Q. score of 130 or above are classified as intellectually gifted. Arshiya's I.Q. of 135 puts her well within this range (representing the top 2% of the population).
2. Outstanding Ability and Multi-Talentedness (All-Rounder): Giftedness is not limited to academic excellence alone. It often manifests as high performance across multiple domains. Arshiya is described as an "all-rounder" who:
- Scores at the top of her class (high academic/cognitive ability),
- Is an international chess player (exceptional logical-mathematical and strategic ability),
- Is a remarkable beat player (exceptional musical/rhythmic ability).

While terms like "smart", "creative", or "intelligent" describe aspects of her abilities, "Gifted" is the comprehensive psychological and educational term that formally classifies an individual possessing both an exceptionally high I.Q. (130+) and outstanding talents in diverse fields. Therefore, Arshiya is best classified as Gifted.
