Answer

Answer: (B) Pyrethrin − Insecticidal activity
(C) Phytoalexins − Antifungal activity

Explanation:
Pyrethrin is known for its insecticidal activity, and phytoalexins have antifungal properties. Anthocyanins are typically involved in attracting pollinators (not herbivore deterrence), and tannins are known for their astringency, not pollinator attraction.
