These bid and ask prices are not chosen at random. They are values based on a mathematical formula, such as the Black-Scholes model. To that model, market makers may decide to add tweaks of their own that depend on the current risk or lack thereof of their positions. The point is that these prices are not chosen at random. The value of an option can be calculated exactly if you know the true number for each of the seven items that go into the equation. In reality, only six of these ways to value options are known, and the seventh volatility must be estimated.

When investors buy calls instead of stock, they have extra cash not used to buy stock and that cash can earn interest.
When rates are higher, they earn more interest, and thus, are willing to pay more to own call options. Dividends — When a stock goes ex-dividend trades without the stockholder receiving that dividendthe stock price declines by the amount of that dividend. Thus, call are worth less, and puts are worth more, as the dividend increases.
Volatility — Volatility is a measure of how much the stock prices varies from day to day. Volatile stocks undergo larger and more frequent price changes than non-volatile stocks.
