Answer B is correct although the structure might seem quite strange to you, if you are unfamiliar with this type of a fragment.
The phrase that starts with "its" is a so-called ABSOLUTE PHRASE.
An absolute phrase combines a noun and a participle with any accompanying modifiers or objects. The pattern looks like this:

noun + participle + optional modifier(s) and/or object(s)

Here are some examples:

Legs quivering

Legs = noun; quivering = participle.

Her arms folded across her chest

Arms = noun; folded = participle; her, across her chest = modifiers.

Our fingers scraping the leftover frosting off the plates

Fingers = noun; scraping = participle; frosting = direct object; our, the, leftover, off the plates = modifiers.

Rather than modifying a specific word, an absolute phrase will describe the whole clause:

Legs quivering, our old dog Gizmo dreamed of chasing squirrels.

Her arms folded across her chest, Professor Hill warned the class about the penalties of plagiarism.
