Below are the choices that I was able to check from other sources:
A. Theo Ballmer
B. Piet Mondrian
C. Adrian Frutiger
The answer is B which is "Piet Mondrian". Pieter Cornelis "Piet" Mondriaan, after 1906 Mondrian, was a Dutch painter. Mondrian was a contributor to the De Stijl art movement and group, which was founded by Theo van Doesburg.
