Please refer to the following screenshot. Given the list of students' names $($first name and last name$)$ and their ID numbers, we want to separate them into three columns: First Name, Last Name, and ID$.$ Which pair of functions can extract the first name of the first student?

$\backslash$table$[[,$A$,$B$,$C$],[1,$Student Name and ID$,$Length,First Name$],[2,$John Milandeep $0018274,,],[3,$Tom Jamal $0012298,,],[4,$Kate Talib $0014406,,],[5,$Jane Meshal $0016061,,]]$

$=$FIND$("",$ A$2)$ in Cell B$2,$ then $=$RIGHT$($A$2,$B$2-1)$ in Cell C$2$

$"A2,1$ in Cell $B2,$ then $=$RIGHT$($A$2,$B$2-1)$ in Cell C$2$

$=$FIND$(""A2,1)$ in Cell B$2,$ then $=$LEFT$($A$2,$B$2-1)$ in Cell C$2$

$=$ FIND$("""$A$2$
