Question

vowels in spanish are pronounced with a lot of
a) tension
b) straining
c) variety
d) looseness​

Answer 1

Answer:

Spanish Vowel Pronunciation

In Spanish, o is much shorter and is pronounced with rounded lips from start to finish (sort of like the vowels you would use in English choral music).

Answer 2

Answer:

Generally speaking, pronouncing vowels in Spanish is a lot less complicated than pronouncing them in English.

So I think the answer for your question is straining.
