A isn't true because 513 is at least divisible by 3, so it's not a prime number.
C isn't true because all whole numbers are either prime or composite.
D isn't true because it is neither a imaginary number, fraction, decimal, or unreal number, so therefore it must be a whole number.
B is true, because it is able to be divided by numbers other than one and itself.

Answer:
Stefan originally spent $110
Stefen made $33 by selling the bicycle and helmet to jin.
Step-by-step explanation:
let ,
the original cost of bicycle and helmet for Stefan be 'x'
now,
total cost for Jin of bicycle and helmet = 126 + 17
= 143
also, total cost for Jin = 130% of original cost for Stefan
⇒ 143 = 
⇒ x = 110.
hence,
profit made by Stefan = total cost for Jin - original cost for Stefan
= 143 - 110
= 33
