The answer is B.
"Grandma taught me to make cheesecake" is the only sentence that makes sense when it stands alone.
I think the questions that must be ask are:
a.What does “encryption” mean?
d.What are “key distribution problems”?
All the text is based on the concept "encryption" so it is very important to know what it means in order to undestand the rest of the information. If not, you will be missing important facts. In addition, there are a lot of words used that are derived from this one, so you won't be able to undestand them.
Another important concept that gives a lot of information just by knowing it's meaning is "key distribution problems", they could be two or a thousand, it is important to know what they are and what they do.
The other question that seems important is the one of the "public key cryphtography" but this one can be inferred by the context.
Answer:
Colmillo Blanco como el Collie.
Explicación:
Cuando White Fang sigue a Collie en lugar de ir con su maestro en su paseo, esto muestra que a Fang blanco le gusta el Collie, que es una perra. White Fang se sintió atraído por el Collie, lo que lo obligó a no ir con su maestro en su paseo y obligó a White Fang a seguir al Collie. La evidencia de este hecho es que al final, White Fang se convierte en padre y Collie se convierte en madre de muchos cachorros.
