Which two signs should be interchanged to make the following equation correct?

$$6 \div 24 + 6 \times 7 − 5 = 29$$

$$\frac{6}{24}+\ 6\times\ 7\ -\ 5=29$$  

Here is the given series need to check with each option 
A. / and *
$$\frac{6}{24}+\ 6\times\ 7\ -\ 5=29$$

$$6\times\ 24\ +\ \frac{6}{7}-5=29$$

$$144\ +\frac{6}{7\ }\ -\ 5=29$$

$$\frac{150}{7}\ -\ 5=29$$

$$16.4=29$$

B. / and +

$$6\ +\ \frac{24}{6}\times\ 7\ -\ 5=29$$

$$6\ +\ 4\times\ 7\ -\ 5=29$$

$$6\ +28-\ 5=29$$

$$34-\ 5=29$$

$$29=29$$

C./ and -

$$6\ +\ 24\ -\ 6\times\ \frac{7}{5}=29$$

$$30-\ \frac{42.5}{5}=29$$

$$30-\ 8.4=29$$

$$21.6=29$$

D. * and +

$$\frac{6}{24}\times\ 6\ +\ 7\ -\ 5=29$$

$$\frac{6}{24}\times\ 6\ +2=29$$

$$\frac{6}{24}\times\ 8=29$$

$$4\times\ 8=29$$

$$32=29$$

Hence option B is the correct answer
