Why is it not recommended to use Vector in new code?

  1. Because it's deprecated

  2. It's not thread-safe

  3. There are better alternatives like ArrayList

  4. Performance issues with large datasets

The correct answer is: There are better alternatives like ArrayList

Although Vector was a commonly used data structure in the past, it is now considered outdated due to advances in technology. As a result, it is not recommended to use Vector in new code. Option A is incorrect because although Vector is technically deprecated, this is not the sole reason for not using it. Option B is also incorrect because it implies that all deprecated data structures should not be used, which is not necessarily true. Option D is partially correct as Vector can have performance issues with large datasets, but this is not the main reason for not using it. Option C, on the other hand, provides the most accurate explanation as there are now better alternatives like ArrayList that offer improved performance and functionality. Therefore, it is not recommended to use Vector in new code as there are more efficient and modern alternatives available.
