Answer: Option 'A' is correct.
Step-by-step explanation:
Since we need to find the geometric sequence ,
For this we find the " common ratio" :
[tex]\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{\frac{1}{4}}{\frac{1}{4}}=\frac{\frac{1}{4}}{\frac{1}{4}}\\\\1=1[/tex]
On the other hand, in options 'B' , 'C' and 'D' , there is no common ratio,
Hence, Option 'A' is correct.
