Explanation

Dragging the second measure onto the vertical (Y) axis of an existing chart tells Tableau to blend both measures onto a single shared axis, creating a combined axis chart rather than generating a separate row. Option A (Marks card) only changes the visual encoding of a single measure. Option B (Filters card) has nothing to do with axis placement. Option C (horizontal axis) would create a dual-axis on the columns dimension, which isn't how row-based combined axes work - both measures live on the Rows shelf sharing one vertical axis.

Memory tip: Think "drop on the spine" - the vertical axis is the spine of a row-based chart, and dropping the second pill there fuses both measures onto that same spine instead of splitting the view into two separate rows.
