Answer:  B. 91,390

Step-by-step explanation:

The combination of n things taken m things at a time is given by :-

^nC_m=\dfrac{n!}{m!(n-m)!}

Given : The total numbers in lottery = 40

The number of correct numbers to win the lottery = 4

Now, the combination of 40 numbers taken 4 correct numbers at a time is given by :-

^{40}C_{4}=\dfrac{40!}{4!(40-4)!}\\\\=\dfrac{40\times39\times38\times37\times36!}{(24)(36!)}=91,390

Hence, there are 91,390 different 4 number combinations .
