Select the option figure in which the given target figure is embedded as its part, provided that rotation is NOT allowed.

By careful observation of the option figures while keeping the orientation of the target figure fixed:In the correct option figure, the exact shape of a right-angled triangle fused with a continuous vertical line along its hypotenuse line can be traced clearly without any modification or rotation.The remaining option figures either lack the matching right-angled intersection or require rotating the shape to fit.
