Understanding the problem:
Let's denote the current age of the son as S and the current age of the parent as P. From the given information, we know that P = 3S.

Setting up the equation:
Five years later, the parent's age will be P + 5 and the son's age will be S + 5. According to the second statement, we can write the equation:
P + 5 = 2.5(S + 5)

Solving the equation:
Substitute P = 3S into the equation:
3S + 5 = 2.5(S + 5)
3S + 5 = 2.5S + 12.5
0.5S = 7.5
S = 15

Calculating the parent's age:
P = 3S
P = 3 * 15
P = 45
Therefore, the parent's current age is 45 years, which is option B.
