Just remember:

👉 The highest number (n) = Period
👉 Last orbital type (s, p, d, f) = Block

The highest value of 𝙣 in this configuration is 𝟒 (from 4s and 4p).
So, the element is in 𝙋𝙚𝙧𝙞𝙤𝙙 𝟒.

The last orbital here is 𝟒𝐩.
Elements in which the 𝙡𝙖𝙨𝙩 electrons enter the p-orbital belong to the 𝙥-𝙗𝙡𝙤𝙘𝙠.

Period 4 → ✅
p-block → ✅
Thus, the correct answer is:
A. Period 4, p-block ✅
