The Correct Option is A
Solution and Explanation
The two-digit numbers that give a remainder of 3 when divided by 7 are of the form $7k + 3$, where $k$ is an integer. We find the two-digit numbers in this form and sum them up. The result is 666.

Scientific research shows that many animals are very intelligent and have sensory and motor abilities that dwarf ours. Dogs are able to detect diseases such as cancer and diabetes and warn humans of impending heart attacks and strokes. Elephants, whales, hippopotamuses, giraffes, and alligators use low-frequency sounds to communicate over long distances, often miles. Many animals also display wide-ranging emotions, including joy, happiness, empathy, compassion, grief, and even resentment and embarrassment. It’s not surprising that animals share many emotions with us because we also share brain structures, located in the limbic system, that are the seat of our emotions.- CAT - 2024
