The following sentence is written correctly:
B. The drum major performed badly because she forgot the routine.
<u>Why not A, C or D?</u>
A. The team played <u>good</u> in their championship game so they won. The word<em> good</em> should be replaced with the word<em> well</em>. An adverb describes a verb, the word well would describe how they played. Good is an adjective that describes a noun.
C. Ivan feels<u> well</u> about his choice to join the after-school program. The word <em>well</em> should be replaced with the word <em>good.</em> Whenever, one says someone is feeling well it refers to their health.
D. The gymnast felt<u> badly</u> because they had skipped breakfast. The word <em>badlly</em> should be replaced with the word <em>bad</em>.
The correct answer is the fourth option. The other three are grammatically incorrect.
