Solution

The correct option is B 53
Here, we can see that both numerator and denominator are approaching to zero. So it's a 0/0 form.
Hence we can apply L'Hospital's rule to find the limit.
Differentiating both Numerator and denominator - limx05(1+x)43+10x
We can see that 0/0 form is removed so we can directly put limit value in the expression.
Therefore the answer will be = 53
