Answer 1

$\large\bf\underline\red{Answer \: :-}$

$\rm\bigstar{\: \: D. \: 3 }$

$\large\bf\underline\red{Explanation \: :-}$

We know,

p(x) = 2x + 1

Now,

$\sf\longrightarrow{p(1) = 2(1) + 1} \\ \\ \sf\longrightarrow{p(1) = 2 + 1} \: \: \: \: \: \: \\ \\ \rm\longrightarrow \pink{p(1) = \underline{3} } \: \: \: \: \: \: \: \: \: \: \:$

Option [D] is the correct answer.

\large\bf\underline\red{Explanation \: :-}

Explanation:−

We know,

p(x) = 2x + 1

Now,

\begin{gathered}\sf\longrightarrow{p(1) = 2(1) + 1} \\ \\ \sf\longrightarrow{p(1) = 2 + 1} \: \: \: \: \: \: \\ \\ \rm\longrightarrow \pink{p(1) = \underline{3} } \: \: \: \: \: \: \: \: \: \: \: \end{gathered}

⟶p(1)=2(1)+1

⟶p(1)=2+1

⟶p(1)=
