I think the answer is D because all the other options have a decimal point e.g. $4.46, (I don't use pounds but I'm assuming it's something like 4 pound 46), 4 hours, 46 minutes. You simply cannot have 0.46 of a dog (unless you're very cruel.)
N.B. I only used 4.46 as an example, it's not the correct number.
Let the middle point be M.
MDC is a isometric triangle.
∠MDC = MCD = 25°
∠DBC = 180-25-25-35 = 95°
