why does achebe most likely use the phrase “frontal attack” instead of “direct approach” or “short-term plan” in this excerpt?

a. to convey mr. brown’s almost militaristic sense of order and discipline
b. to imply that mr. brown’s motives are ultimately hostile to the igbo people
c. to show that mr. brown considers his charitable work a matter of life and death
d. to illustrate how much of a struggle it would be for mr. brown to convert the igbo people
