(B) To determine the block of an element,we look at the subshell in which the last electron enters:$1. Z = 33$ (Arsenic): $[Ar] 3d^{10} 4s^2 4p^3$ ($p$-block)$2. Z = 47$ (Silver): $[Kr] 4d^{10} 5s^1$ ($d$-block)$3. Z = 53$ (Iodine): $[Kr] 4d^{10} 5s^2 5p^5$ ($p$-block)$4. Z = 59$ (Praseodymium): $[Xe] 4f^3 6s^2$ ($f$-block)$5. Z = 68$ (Erbium): $[Xe] 4f^{12} 6s^2$ ($f$-block)$6. Z = 74$ (Tungsten): $[Xe] 4f^{14} 5d^4 6s^2$ ($d$-block)$7. Z = 82$ (Lead): $[Xe] 4f^{14} 5d^{10} 6s^2 6p^2$ ($p$-block)Since these elements include $p, d,$ and $f$ blocks,the correct option is $B$.

Elements having atomic numbers $33, 47, 53, 59, 68, 74, 82$ are present in which blocks of the periodic table?
