Given below are four jumbled sentences. Select the option that gives their correct logical sequence.
A. When we connect this design with a wire, electricity flows.
B. These metal strips were put in a sulphuric acid solution.
C. He made two strips of different metals.
D. Alessandro Volta discovered electric battery.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. DCBA.
The correct sequence starts with 'D', where Alessandro Volta discovered the electric battery.
Next, 'C' explains that he made two strips of different metals, which were then placed in a sulphuric acid solution as described in 'B'.
Finally, 'A' illustrates the result, where connecting the design with a wire causes electricity to flow.
Correct sequence: D → C → B → A
This sequence follows the logical progression of Volta’s discovery and its application.
