- B actinomorphic

Correct answer: B. actinomorphic
Explanation: ⊕ marks an actinomorphic (radially symmetrical) flower, which can be cut into equal halves through any diameter.
In a dicot stem, vascular bundles are arranged in a single ring (with cambium between xylem and phloem, enabling secondary growth); in a monocot stem, bundles are scattered throughout with no cambium, so monocots can't undergo secondary growth (no wood formation).
