1. The problem asks us to find the product of 890 and 77 using long multiplication. 2. Long multiplication involves multiplying each digit of the second number by the entire first number, then adding the results appropriately. 3. Multiply 890 by 7 (the units digit of 77): $$890 \times 7 = 6230$$ 4. Multiply 890 by 70 (the tens digit of 77, which is 7 tens): $$890 \times 70 = 62300$$ 5. Add the two results: $$6230 + 62300 = 68530$$ 6. Therefore, the product of 890 and 77 is $68530$. 7. The correct answer is option c. 68530.
