aComputed only for a 2 × 2 table
b2 cells (50.0%) have expected count less than 5. The minimum expected count is 1.02.
A.
The Fisher's exact p-value = 0.268.
B.
The likelihood ratio = 1.340.
C.
The chi-square statistic = 1.437.
D.
The chi-square p-value = 0.231.
Obese

Explanation / Answer
From the given SPSS output
the following findings listed
p value = 0.268
So option D is correct
if expected frequency is less than 5 then fisher exact p value is considered
