When designing a water bottle for a Kindergarten child, the primary factor to consider is
Usability. This encompasses:
- Ease of handling for small hands (lightweight, ergonomic shape).
- Safety (non-toxic materials, no sharp edges).
- Appropriate size and capacity for a young child.
- Simple and appealing design that attracts children.
Complex designs, luxury materials, or very large capacities are unsuitable for young children due to potential difficulty in use or safety concerns.
Explanation of Other Options:
(B) Complex Design: May impede usability.
(C) High-end Luxury Material: Impractical and unnecessary for children.
(D) Large Capacity: May render the bottle too heavy and bulky for a child.
Therefore, the correct answer is option
(A).
