Explanation

BitLocker To Go is Microsoft's full-disk encryption feature designed specifically for removable storage devices such as USB flash drives and external hard drives. When a USB drive is protected with BitLocker To Go, the entire drive is encrypted. Files on the drive are completely inaccessible until the user provides the correct authentication - typically a password or smart card PIN. Without it, the data appears as unreadable encrypted content. Read-only access (A) restricts modification but still allows viewing files. Secure Boot (B) is a UEFI firmware feature that prevents unauthorized OS loading, not file-level encryption. System files and folders (C) may be hidden or restricted but are not encrypted in this way. BitLocker To Go is the only option that specifically encrypts a USB drive and gates access behind authentication.
