Derive the Black‑Scholes PDE step by step. What assumptions are made? Q129 - Q130: What is the Black‑Scholes formula for a European call option? Walk through the logic of replicating a call. Q131 - Q132: Explain why the drift (µ) disappears from the Black‑Scholes equation. Q133 - Q134: What are the limitations of Black‑Scholes (e.g., constant volatility, no jumps)?
