[ALGO] LCS - self doubt

Question

Consider two strings A = “12341” and B = “341213”.

The length of LCS is 3 and they are "121", "123", "341"

Now there are two possibilities for the subsequence "341"

now i want to ask what should be the total no. of subsequence possible 3 or 4(because of two possibilities of "341")

Comments

I think it should be 3

why ?

@ashish pal 

There is no two possibility for $'341'$

I got only one possibility for each subsequence.
