When using the noun 'choice' to refer to the act of choosing something, there are two possible translations in Spanish:

• elección (pronounced: eh-lek-SYOHN)
• opción (pronounced: ohp-SYOHN)

Both are feminine nouns. Here are some example sentences:

• Creo que has hecho una buena elección. (I think that you have made a good choice.)
• No sé qué oferta aceptar. Es una elección difícil. (I don't know which offer to take. It's a difficult choice.)
• Tengo que hacer el examen mañana. No me queda otra opción. (I have to do the exam tomorrow. I have no choice.)

The use of 'choice' in the sense of 'variety' or 'range of options' is translated as:

• surtido (pronounced: soor-TEE-doh)
• variedad (pronounced: bah-ryeh-DAHD)

Notice that surtido is a masculine noun, but variedad is a feminine one. Use them in examples such as these:

• En esa tienda venden un amplio surtido de quesos. (In that store they sell a wide assortment of cheeses.)
• La cafetería ofrece una gran variedad de postres. (The coffee shop offers a great choice of desserts.)
