Step 1: Approach
Place every element in its block using atomic number and group.
Step 2: Placement
Mn 25, Ag 47, Zr 40, Au 79, Mo 42 and Pt 78 all fill their d orbitals and sit in the middle block of the periodic table. Sn has atomic number 50 and its outer electrons are $5s^2 5p^2$, so it is a p-block metal. Pm has atomic number 61 and fills the 4f subshell, so it is a lanthanoid.
Step 3: Conclusion
Only option (D) contains no d-block element.
Final Answer:
Tin is a p-block metal and promethium is an f-block lanthanoid, so option (D) has no transition element.
\[ \boxed{\text{Sn and Pm}} \]
