The graph shows the estimated boiling point $y$, in degrees Celsius, of a straight-chain alkane with a molecular weight of $x$ grams per mole, where $1\le x\le 280$. Which statement is the best interpretation of the point $(155.21,196.74)$?

A

A straight-chain alkane with a molecular weight of $196.74$ grams per mole has an estimated boiling point of $155.21$ degrees Celsius.

B

A straight-chain alkane with a molecular weight of $155.21$ grams per mole has an estimated boiling point of $196.74$ degrees Celsius.

C

The minimum estimated boiling point for straight-chain alkanes corresponds to an alkane with a molecular weight of $155.21$ grams per mole and an estimated boiling point of $196.74$ degrees Celsius.

D

The maximum estimated boiling point for straight-chain alkanes corresponds to an alkane with a molecular weight of $155.21$ grams per mole and an estimated boiling point of $196.74$ degrees Celsius.
