Wifi/internet usage has sharply increased in recent times.
Assumption I : Internet data has become cheaper.
Assumption II : During lockdown time, people were afraid to go out.

The correct answer is (C) Assumption I and II are strong.

• Logical Principle: In critical reasoning, an assumption is an implicit premise that explains the cause behind an observed phenomenon. We must evaluate if both factors logically contribute to the trend of increased internet usage.
• Deduction: 1) Decreased cost of internet data (Assumption I) directly increases affordability and accessibility, leading to higher consumption. 2) Lockdown restrictions (Assumption II) necessitated staying indoors, which forced individuals to rely on the internet for work, education, and entertainment, thereby driving usage upward.
• Verification: Both assumptions provide logical, independent causes that validate the recent surge in internet usage. Since both factors are relevant contributors to the phenomenon, option (C) is the most accurate choice. Other options are incorrect as they ignore the validity of one or both contributing factors.
