Answer & Solution
Answer: Option B
Solution:
Combining filters like <feComposite> and <feColorMatrix> affects the appearance of SVG elements by blending two input images or operations based on an alpha mask and applying color transformations. <feComposite> blends elements using various operations like over, in, out, atop, etc., while <feColorMatrix> applies color adjustments, resulting in blended and color-modified elements. This combination is useful for creating composite effects, layering graphics, or applying color transformations with precise control over blending modes, contributing to visually appealing and sophisticated SVG designs.
