I. Sonali received a phone call at 9:15 a.m. at her home
II. Sonali's car reached office at 10:15 a.m., 45 minutes after she left her residence.

• A. If the data in statement I alone are sufficient to answer the question
• B. If the data in statement II alone are sufficient answer the question
• C. If the data either in I or II alone are sufficient to answer the question;

Answer 1

The correct option is B If the data in statement II alone are sufficient answer the question

From statement II, we conclude that Sonali left her home $45$ minutes before $10:15$ a.m. i.e, $9:30$ a.m.
Thus, only Il is needed
option B
