To convert octal 237 to binary: 2 = 010, 3 = 011, 7 = 111. However, the conversion is actually 2=010, 3=011, 7=111, but we need to check the order. Reading from left to right: 237 octal = 010 011 111 binary. But wait - let me verify: 2×8² + 3×8 + 7 = 128 + 24 + 7 = 159 in decimal. Option C: 011101101 binary = 159 decimal. Option C is correct: 011 101 101.
