The best inference that explains why Susan
B. Anthony believed her crime is alleged is that she could use the Constitution to prove that she did not commit any crime while voting.
Step-by-step explanation:
The preamble of the Constitution of the United States was in Susan's view the greatest testimony of gender equality and equal rights to both men and women.
She emphasised on the fact that the constitution does not specifically guarantee the rights only to the white male citizens as it does not have any phrase quoting anything like that.
Hence, she believed and tried to prove that it was her right to vote in the Presidential elections.
