What shadow effect is applied by shadow-lg in Bootstrap?

Bootstrap provides different shadow utilities like shadow-sm, shadow, and shadow-lg. Which of these best describes the visual effect of shadow-lg?

Bootsrap

<div class="shadow-lg p-3 mb-5 bg-white rounded">Shadow Large Example</div>

A A colored shadow with a red tint around the element.

B A large, prominent shadow with more blur and spread around the element.

C No shadow effect; it removes any shadow from the element.

D A small, subtle shadow with minimal blur and offset.

The shadow-lg class applies a larger, more noticeable shadow with greater blur and spread compared to shadow-sm or shadow. It makes the element stand out more visually.
