The strike price is the price at which a buyer of a call option can buy the security while for put options it is the price at which the security can be sold. The strike price is fixed in the contract and does not fluctuate with any change in the underlying script.
The strike prices are decided by the exchange based on the volatility in the underlying script which previously was decided based on the denomination of the script.
