The correlation coefficient between the variables are always between +1 and -1
If the correlation coefficient is near to +1 the degree of relationship between variables is strongly positively correlated. And if the correlation coefficient is near to -1 the degree of relationship between variables is strongly negatively correlated.
Hence at the extremes +1 and -1, there is a strong degree of relationship between two variables
Near to 0 (the middle of the range), there is a weak degree of relationship between two variables
So, the answer would the value the is nearest to 0 since we want a weak relationship
The value that is nearest to 0 is a) 0.10
So, the answer is a)0.10
