THE VALUE C IS NUMBER 4 WHICH IS 84 DEGREES WHICH IS AND OBTUSE ANGLE
Given
The options are given for the multiplicative identity property.
Explanation
To determine the multiplicative identity property.
Any number multiplied by 1, gives the same result as the number itself. It is called identity property of multiplication.
Then from the options

Answer
Hence the correct options are
B and D.
110
2 and 5 are prime and thus share no common factors. The lowest common multiple of 2 and 5 is therefore 2 x 5 = 10.
Your answer must be a multiple of 10 and there is only one answer in that range that fits.
Double-check:
110 / 2 = 55 r. 0
110 / 5 = 22 r. 0
11 because the greatest you value was 11 so 11 should be the right awnswer
