How many members must approve a bill in the New Jersey Senate for it to pass?

In the New Jersey Senate, a bill requires a majority approval from its members for it to pass. The Senate comprises 40 members, so a majority would be defined as more than half of the total. Consequently, 21 votes are necessary for a bill to pass, which represents a simple majority of the 40 members. This requirement is rooted in ensuring that any legislation has support from a sufficient number of elected representatives, reflecting the collective will of the Senate.

The other options are incorrect because they exceed the number of total members in the Senate or do not satisfy the majority needed for passage.
