we have that
negative 3, left-parenthesis space right-parenthesis, negative 1 and one-eighth
[-3,( ),-1,1/8]
we know that
the number to insert must be between -3 and -1------> (-3,-1)
A. negative 3 and one-half -------> is not in the interval (-3,-1)
B. 0 -------> is not in the interval (-3,-1)
C. negative 2 and one-fourth ----> -2 1/4 belong to the interval (-3,-1)
D. one and one-half -------> is not in the interval (-3,-1)
therefore
the answer is the option
C. negative 2 and one-fourth
