Answer 1

• {thermometer, fridge, rusty nail, deoderant}
• {credit card, face wash, tweezers, shovel}
• {clothes, glass, car, greeting card}

Explanation:

The options that will be equivalent to T will have to be the options that have the same Cardinality as T. Cardinality refers to the number of elements in a set and in the set T, there are 4 elements being Tinkey-Winky, Laa-Laa, Dipsy, Po so the Cardinality is 4.

The equivalent sets would therefore be sets with a cardinality of 4 as well and those are;

• {thermometer, fridge, rusty nail, deoderant}
• {credit card, face wash, tweezers, shovel}
• {clothes, glass, car, greeting card}
