Select the most appropriate option to fill in the blank.

Accuracy rates of facial recognition algorithms are ______ low in the case of minorities, women and children, as demonstrated in multiple studies across the world.

Particularly

The most appropriate option to fill in the blank is particularly.

The sentence is about how facial recognition algorithms are less accurate in the case of minorities, women and children. The word "particularly" means "to a special or greater extent." This is the most appropriate word because it accurately describes how facial recognition algorithms are significantly less accurate in the case of minorities, women and children.

The other options are not as appropriate.

• Smoothly means "without difficulty or disruption." This does not make sense in the context of the sentence, because the accuracy of facial recognition algorithms is not a smooth process.
• Carelessly means "without taking care or attention." This does not make sense in the context of the sentence, because the inaccuracy of facial recognition algorithms is not due to carelessness.
• Beautifully means "in a way that is very pleasing to the senses." This does not make sense in the context of the sentence, because the inaccuracy of facial recognition algorithms is not beautiful.
