In this question, you need to price options with various approaches. You will consider puts and calls on a share. Please read following instructions carefully:

• The spot price of this share will be determined by your student number. You need to use the last digit of your student number. The spot price of the share will be (last digit of your student number*10+6). For example, if the last digit of your student number is 5, the spot share price will be 5*10+6=56. If the last digit of your student number is 0, please replace it with 4, i.e. the spot price will be 4*10+6=46.
• The strike price of the options will be the share price you just calculated +2. For example, if the share price you calculated based on your student number is 56, the strike price of the options will be (56+2)=58.

Based on this spot price and this strike price as well as the fact that the risk-free interest rate is 6% per annum with continuous compounding, please undertake option valuations and answer related questions according to following instructions:
