I’m pretty sure it would be c. el peor
Cantante = singer (masc. or fem.) - el cantante, la cantante
bailarín = dancer (masc.) - el bailarín
atleta = athelete (masc. or fem.) - el atleta, la atleta
joven = young / young person (masc. or fem.) - el joven, la joven
B. Bailarín can refer to a boy, but not a girl, because the feminine is bailarina. All the others can refer to both boy or girl.
Clarification:
I found the complete instructions for the exercise online:
Match the sentence with a step of the scientific method listed below.
Answer:
d. test hypothesis/experiment
Explanation:
To complete this exercise, you have to select the correct step of the scientific method that is described in the sentence given. The <u>correct step is "d"</u> because it is the one where you test your hypothesis, you do the experiment, and the sentence describes a process where there are different things to try to see the results: five pots exposed to sunlight and five pots inside a house.
