The correct answer is A. Rs 125.00.
A call option is a contract that gives the buyer the right, but not the obligation, to buy a specified amount of an underlying asset at a specified price on or before a specified date. The seller of the call option is obligated to sell the asset at the specified price if the buyer exercises the option.
In this case, the value of the stock is Rs 250 and the call option obligation is Rs 100. This means that the buyer of the call option has the right to buy the stock at a price of Rs 100, even if the market price of the stock is higher than Rs 100.
If the market price of the stock is below Rs 100, the buyer of the call option will not exercise the option, and the seller of the call option will not be obligated to sell the stock.
If the market price of the stock is above Rs 100, the buyer of the call option will exercise the option, and the seller of the option will be obligated to sell the stock at a price of Rs 100.
In this case, the current value of the portfolio is Rs 125. This is because the buyer of the call option has the right to buy the stock at a price of Rs 100, even though the market price of the stock is Rs 250.
Option A is the correct answer because it is the only option that is consistent with the information given in the question. Option B is incorrect because it is the value of the stock, not the value of the portfolio. Option C is incorrect because it is the sum of the value of the stock and the call option obligation, which is not the value of the portfolio. Option D is incorrect because it is the value of the call option obligation, not the value of the portfolio.
