Solution:

Understanding the problem:
- When a head appears, 2 points are awarded and when a tail appears, 1 point is awarded.
- To get an odd number of points, we need to get either 1 point or 3 points in total.

Possible Outcomes:
- When three coins are tossed simultaneously, there are a total of 8 possible outcomes: (HHH, HHT, HTH, THH, HTT, THT, TTH, TTT)

Favorable Outcomes:
- Out of the 8 possible outcomes, 4 outcomes result in an odd number of points: (HHT, HTH, THH, TTT)

Calculating Probability:
- Probability = (Number of favorable outcomes) / (Total number of outcomes)
- Probability = 4 / 8 = 1/2
Therefore, the probability of getting a total of an odd number of points when three unbiased coins are tossed simultaneously is 1/2. So, the correct answer is option 'A'.
