Huge aberration in options price

Banknifty Futures moved to highest of + 100points(H=24411 - O=24311) at 10:15am (1minute candle reference)

While 24200 CE moved to a highest of +160points (H=655-O=495) as shown in image with a delta of <1 when the spot/futures moved by 100points.

How is that possible?

spike in option prices like this is normal… here you are only accounting for delta, while forgetting other greeks like vega especially… if volatility increases price of option will spike as well.
