The table below shows the scores on an end-of-year project of 10 randomly selected architecture students andthe number of days each student spent working on the project. $\begin{array}{|l|c|c|c|c|c|c|c|c|c|c|}
\hline \text { Days, } \mathrm{x} & 5 & 7 & 4 & 10 & 4 & 6 & 6 & 7 & 8 & 5 \
\hline \text { Score, } \mathrm{y} & 73 & 88 & 68 & 96 & 74 & 86 & 93 & 98 & 98 & 79 \
\hline
\end{array}$

A) $\mathrm { r } = 0.847$; linear relation exists
B) $\mathrm { r } = 0.847$; no linear relation exists
C) $\mathrm { r } = 0.761$; linear relation exists
D) $\mathrm { r } = 0.761$; no linear relation exists
