✅ B — the CAPACITOR!
🔲 Inside: two metal plates with an insulator between them.
➕➖ Connect it to a battery: plus piles up on one plate, minus on the other — and it stays there.
⚡ It can let it all out in a flash — like a tiny, super-fast battery (that's how a camera flash works).
(A resistor turns energy into heat, a diode is a one-way valve, an LED makes light — none of them store charge.)
