Answer:
We have been given many sequences below:
The sequence is said to be geometric if there is same ratio between consecutive terms

So we will check all the sequences one by one:
(1) 

.
Hence, geometric
(2) 


Hence, geometric.
(3) 


Hence, geometric.
(4) 


Hence, geometric.
(5) 

Ratio is not same hence, not geometric.
Answer:
B.
