1. You are developing a Silverlight 4 application that uses the isolated storage. The application you just created is a module of a bigger application already running. Your newly created application will need 6 MB of free space in the isolated storage. You need to ensure that the minimum amount of space needed to save those 6 MB is requested. Which code snippet should you use?

a. Using(IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()) { isf.IncreaseQuotaTo(6291456) });

b. Using(IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()) { isf.IncreaseQuotaTo(isf.UsedSize+6291456) });

c. Using(IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()) { isf.IncreaseQuota (6291456) });

d. Using(IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication()) { isf.IncreaseQuotaTo(isf.AvaliableSpace+6291456) });
