His favorite player was just named MVP.c.)Jennifer told Rebecca that her lunch was getting cold. She wouldn't want to see the food go to waste.d.)Michael runs a graphic design business with Mark.

The pair of sentences that uses pronouns to effectively create cohesion is a.) Sara and Anil have three dogs. They like to take walks in the park on Sundays.

Here's why:

a.) "Sara and Anil have three dogs. They like to take walks in the park on Sundays." - The pronoun "They" refers clearly to Sara and Anil, creating cohesion between the two sentences.

b.) "Linus and Ryan both love baseball. His favorite player was just named MVP." - The pronoun "His" is ambiguous. It's unclear whether it refers to Linus or Ryan, so it doesn't create effective cohesion.

c.) "Jennifer told Rebecca that her lunch was getting cold. She wouldn't want to see the food go to waste." - The pronouns "her" and "she" are ambiguous. It's unclear whether they refer to Jennifer or Rebecca, so they don't create effective cohesion.

d.) "Michael runs a graphic design business with Mark. It has done very well this year." - The pronoun "It" refers clearly to the graphic design business, creating cohesion between the two sentences. However, the question asks for the use of pronouns to create cohesion, and "it" is a neutral pronoun that doesn't refer to any specific noun in the previous sentence. Therefore, option a is a better example of using pronouns to create cohesion.
