Concept:
Mural painting techniques are methods used for painting on walls, ceilings and architectural surfaces.
Important mural techniques include fresco, fresco buono, fresco secco and related wall-painting methods.
Step 1: Understand Buono and Secco.
In mural painting:
\[
\text{Buono} = \text{painting on wet plaster}
\]
\[
\text{Secco} = \text{painting on dry plaster}
\]
These terms are directly connected with mural technique.
Step 2: Check other options.
Gouache is a water-based opaque painting medium, not specifically a mural technique.
Madhuchista Vidhana is associated with lost-wax metal casting.
Dry wall art is not the standard technical term asked here.
Step 3: Final conclusion.
Therefore, the mural technique is:
\[
\boxed{\text{Buono Secco}}
\]
Hence:
\[
\boxed{\text{(A)}}
\]
