(D) For a quadratic polynomial of the form $ax^2 + bx + c$,the sum of the zeros $\alpha + \beta$ is given by the formula $\alpha + \beta = -b/a$.Comparing $p(x) = x^2 - 4x + 3$ with $ax^2 + bx + c$,we get $a = 1$,$b = -4$,and $c = 3$.Substituting these values into the formula: $\alpha + \beta = -(-4)/1 = 4/1 = 4$.Since $4$ is a positive integer,the correct option is $D$.

For the polynomial $p(x) = x^2 - 4x + 3$,the value of $\alpha + \beta$ is . . . . . . .
