  • A
    $25$
  • ✓
    $26$
  • C
    $24$
  • D
    $0$
✓

Answer

Correct option: B.
$26$
$26$
$\text{a}^{25^{0}}+\text{a}^{0^{25}}$
$=\text{a}^{1}+\text{a}^{0}$ $\Big(\text{As, }25^{0}=1\text{ and }0^{25}=0\Big)$
$=\text{a}+1$ $\Big(\text{As, }\text{a}^{0}=1\Big)$
$=25+1$
$=26$
Hence, the correct alternative is option $(b)$.
