Which of the assumptions of the Black-Scholes equation is the most problematic?

Conversely, a higher strike price, a shorter term and/ or less volatility yields a lower value.
Why is Black Scholes model important?

What Black-Scholes assumption does the Heston model relax?

What are D1 and D2 in Black-Scholes?
