I claim the ornamental design for a faucet, as shown and described.
FIG. 1 is a perspective view of the claimed design;
FIG. 2 is a front view of the claimed design;
FIG. 3 is a rear view of the claimed design;
FIG. 4 is a top view of the claimed design;
FIG. 5 is a bottom view of the claimed design;
FIG. 6 is a side view of the claimed design; and,
FIG. 7 is another side view of the claimed design.
The ornamental design that is claimed is shown in the drawings as solid lines and surfaces having surface shading. The broken lines in the drawings are for illustrative purposes only and form no part of the claimed design. For example, broken lines formed by equal length dashes show unclaimed portions of the design.
